United States Marine Corps

As outlined in 10 U.S.C. § 5063 and as originally introduced under the National Security Act of 1947, three primary areas of responsibility for the U.S. Marine Corps are:

• Seizure or defense of advanced naval bases and other land operations to support naval campaigns;
• Development of tactics, technique, and equipment used by amphibious landing forces in coordination with the Army and Air Force; and
• Such other duties as the President or Department of Defense may direct.

This last clause derives from similar language in the Congressional acts "For the Better Organization of the Marine Corps" of 1834, and "Establishing and Organizing a Marine Corps" of 1798. In 1951, the House of Representatives' Armed Services Committee called the clause "one of the most important statutory – and traditional – functions of the Marine Corps". It noted that the Corps has more often than not performed actions of a non-naval nature, including its famous actions in Tripoli, the War of 1812, Chapultepec, and numerous counter-insurgency and occupational duties (such as those in Central America, World War I, and the Korean War). While these actions are not accurately described as support of naval campaigns nor as amphibious warfare, their common thread is that they are of an expeditionary nature, using the mobility of the Navy to provide timely intervention in foreign affairs on behalf of American interests.^[17]

The Marine Band, dubbed the "President's Own" by Thomas Jefferson, provides music for state functions at the White House.^[18] Marines from Ceremonial Companies A & B, quartered in Marine Barracks, Washington, D.C., guard presidential retreats, including Camp David, and the marines of the Executive Flight Detachment of HMX-1 provide helicopter transport to the President and Vice President, with the radio call signs "Marine One" and "Marine Two", respectively.^[19] The Executive Flight Detachment also provides helicopter transport to Cabinet members and other VIPs. By authority of the 1946 Foreign Service Act, the Marine Security Guards of the Marine Embassy Security Command provide security for American embassies, legations, and consulates at more than 140 posts worldwide.^[20]

The relationship between the Department of State and the U.S. Marine Corps is nearly as old as the Corps itself. For over 200 years, marines have served at the request of various Secretaries of State. After World War II, an alert, disciplined force was needed to protect American embassies, consulates, and legations throughout the world. In 1947, a proposal was made that the Department of Defense furnishes Marine Corps personnel for Foreign Service guard duty under the provisions of the Foreign Service Act of 1946. A formal Memorandum of Agreement was signed between the Department of State and the Secretary of the Navy on 15 December 1948, and 83 marines were deployed to overseas missions. During the first year of the program, 36 detachments were deployed worldwide.^[21]

Historical mission

The Marine Corps was founded to serve as an infantry unit aboard naval vessels and was responsible for the security of the ship and its crew by conducting offensive and defensive combat during boarding actions and defending the ship's officers from mutiny; to the latter end, their quarters on the ship were often strategically positioned between the officers' quarters and the rest of the vessel. Continental Marines manned raiding parties, both at sea and ashore. America's first amphibious assault landing occurred early in the Revolutionary War on 3 March 1776 as the Marines gained control of Fort Montagu and Fort Nassau, a British ammunition depot and naval port in New Providence, the Bahamas. The role of the Marine Corps has expanded significantly since then; as the importance of its original naval mission declined with changing naval warfare doctrine and the professionalization of the naval service, the Corps adapted by focusing on formerly secondary missions ashore. The Advanced Base Doctrine of the early 20th century codified their combat duties ashore, outlining the use of marines in the seizure of bases and other duties on land to support naval campaigns.

Throughout the late 19th and 20th centuries, Marine detachments served aboard Navy cruisers, battleships and aircraft carriers. Marine detachments served in their traditional duties as a ship's landing force, manning the ship's weapons and providing shipboard security. Marine detachments were augmented by members of the ship's company for landing parties, such as in the First Sumatran expedition of 1832, and continuing in the Caribbean and Mexican campaigns of the early 20th centuries. Marines developed tactics and techniques of amphibious assault on defended coastlines in time for use in World War II.^[22] During World War II, marines continued to serve on capital ships. They often were assigned to man anti-aircraft batteries.

In 1950,^[23] President Harry Truman responded to a message from U.S. Representative Gordon L. McDonough. McDonough had urged President Truman to add Marine representation on the Joint Chiefs of Staff. President Truman, writing in a letter addressed to McDonough, stated that "The Marine Corps is the Navy's police force and as long as I am President that is what it will remain. They have a propaganda machine that is almost equal to Stalin's." McDonough then inserted President Truman's letter, dated 29 August 1950, into the Congressional Record. Congressmen and Marine organizations reacted, calling President Truman's remarks an insult and demanded an apology. Truman apologized to the Marine commandant at the time, writing, "I sincerely regret the unfortunate choice of language which I used in my letter of August 29 to Congressman McDonough concerning the Marine Corps." While Truman had apologized for his metaphor, he did not alter his position that the Marine Corps should continue to report to the Navy secretary. He made amends only by making a surprise visit to the Marine Corps League a few days later, when he reiterated, "When I make a mistake, I try to correct it. I try to make as few as possible." He received a standing ovation.^[24]

When gun cruisers were retired by the 1960s, the remaining Marine detachments were only seen on battleships and carriers. Its original mission of providing shipboard security ended in the 1990s.

Capabilities

The Marine Corps fulfills a critical military role as an amphibious warfare force. It is capable of asymmetric warfare with conventional, irregular, and hybrid forces. While the Marine Corps does not employ any unique capabilities, as a force it can rapidly deploy a combined-arms task force to almost anywhere in the world within days. The basic structure for all deployed units is a Marine Air-Ground Task Force (MAGTF) that integrates a ground combat element, an aviation combat element and a logistics combat element under a common command element. While the creation of joint commands under the Goldwater–Nichols Act has improved inter-service coordination between each branch, the Corps's ability to permanently maintain integrated multi-element task forces under a single command provides a smoother implementation of combined-arms warfare principles.^[25]

U.S. Marines from the 31st Marine Expeditionary Unit training

The close integration of disparate Marine units stems from an organizational culture centered on the infantry. Every other Marine capability exists to support the infantry. Unlike some Western militaries, the Corps remained conservative against theories proclaiming the ability of new weapons to win wars independently. For example, Marine aviation has always been focused on close air support and has remained largely uninfluenced by air power theories proclaiming that strategic bombing can single-handedly win wars.^[22]

This focus on the infantry is matched with the doctrine of "Every marine [is] a rifleman", a precept of Commandant Alfred M. Gray, Jr., emphasizing the infantry combat abilities of every marine. All marines, regardless of military specialization, receive training as a rifleman; and all officers receive additional training as infantry platoon commanders.^[26] During World War II at the Battle of Wake Island, when all of the Marine aircraft were destroyed, pilots continued the fight as ground officers, leading supply clerks and cooks in a final defensive effort.^[27] Flexibility of execution is implemented via an emphasis on "commander's intent" as a guiding principle for carrying out orders, specifying the end state but leaving open the method of execution.^[28]

The amphibious assault techniques developed for World War II evolved, with the addition of air assault and maneuver warfare doctrine, into the current "Operational Maneuver from the Sea" doctrine of power projection from the seas.^[11] The Marines are credited with the development of helicopter insertion doctrine and were the earliest in the American military to widely adopt maneuver-warfare principles, which emphasize low-level initiative and flexible execution. In light of recent warfare that has strayed from the Corps's traditional missions,^[29] the Marines have renewed an emphasis on amphibious capabilities.^[30]

Marines from the 15th Marine Expeditionary Unit depart USS Tarawa (LHA-1), using both a Landing Craft Utility and CH-53E "Super Stallion" helicopters, during amphibious operations in Kuwait, 2003.

The Marine Corps relies on the Navy for sealift to provide its rapid deployment capabilities. In addition to basing a third of the Fleet Marine Force in Japan, Marine expeditionary units (MEU) are typically stationed at sea so they can function as first responders to international incidents.^[31] To aid rapid deployment, the Maritime Pre-Positioning System was developed: fleets of container ships are positioned throughout the world with enough equipment and supplies for a marine expeditionary force to deploy for 30 days.

Doctrine

Two small manuals published during the 1930s established USMC doctrine in two areas. The Small Wars Manual laid the framework for Marine counter-insurgency operations from Vietnam to Iraq and Afghanistan while the Tentative Landing Operations Manual established the doctrine for the amphibious operations of World War II. "Operational Maneuver from the Sea" was the doctrine of power projection in 2006.^[11]

United States Army

The United States Army (USA) is the land service branch of the United States Armed Forces. It is one of the eight U.S. uniformed services, and is designated as the Army of the United States in the U.S. Constitution. The oldest and most senior branch of the U.S. military in order of precedence, the modern U.S. Army has its roots in the Continental Army, which was formed on 14 June 1775 to fight the American Revolutionary War (1775–1783)—before the United States was established as a country. After the Revolutionary War, the Congress of the Confederation created the United States Army on 3 June 1784 to replace the disbanded Continental Army. The United States Army considers itself to be a continuation of the Continental Army, and thus considers its institutional inception to be the origin of that armed force in 1775.

The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control.

First Barbary War

The First Barbary War (1801–1805), also known as the Tripolitan War and the Barbary Coast War, was a conflict during the Barbary Wars, in which the United States and Sweden fought against Tripolitania. Tripolitania had declared war against Sweden and the United States over disputes regarding tributary payments made by both states in exchange for a cessation of Tripolitatian commerce raiding at sea. United States President Thomas Jefferson refused to pay this tribute. Sweden had been at war with the Tripolitans since 1800.

Maj. Samuel Nicholas, first Commandant of the Marine Corps, was nominated to lead the Continental Marines by John Adams in November 1775.

The United States Marine Corps traces its roots to the Continental Marines of the American Revolutionary War, formed by Captain Samuel Nicholas by a resolution of the Second Continental Congress on 10 November 1775, to raise two battalions of marines. This date is celebrated as the birthday of the Marine Corps. Nicholas was nominated to lead the Marines by John Adams.^[32] By December 1775, Nicholas raised one battalion of 300 men by recruitment in his home city of Philadelphia.

In January 1776, the Marines went to sea under the command of Commodore Esek Hopkins and in March undertook their first amphibious landing, the Battle of Nassau in the Bahamas, occupying the British port of Nassau for two weeks.^[33] On 3 January 1777, the Marines arrived at the Battle of Princeton attached to General John Cadwalader's brigade, where they had been assigned by General George Washington; by December 1776, Washington was retreating through New Jersey and, "in desperate need of veteran soldiers," had ordered Nicholas and the Marines to attach themselves to the Continental Army. The Battle of Princeton, where the Marines along with General Cadwalader's brigade were personally rallied by Washington, was the first land combat engagement of the Marines; an estimated 130 marines were present at the battle.^[33]

At the end of the American Revolution, both the Continental Navy and Continental Marines were disbanded in April 1783. The institution was resurrected on 11 July 1798; in preparation for the Quasi-War with France, Congress created the United States Marine Corps.^[34] Marines had been enlisted by the War Department as early as August 1797^[35] for service in the newly-built frigates authorized by the Congressional "Act to provide a Naval Armament" of 18 March 1794,^[36] which specified the numbers of marines to recruit for each frigate.{{^[37]}}

The Marines' most famous action of this period occurred during the First Barbary War (1801–1805) against the Barbary pirates,^[38] when William Eaton and First Lieutenant Presley O'Bannon led 8 marines and 500 mercenaries in an effort to capture Tripoli. Though they only reached Derna, the action at Tripoli has been immortalized in the Marines' Hymn and the Mameluke sword carried by Marine officers.^[39]

War of 1812 and afterward

During the War of 1812, Marine detachments on Navy ships took part in some of the great frigate duels that characterized the war, which were the first and last engagements of the conflict. Their most significant contribution was holding the center of General Andrew Jackson's defensive line at the 1815 Battle of New Orleans, the final major battle and one of the most one-sided engagements of the war. With widespread news of the battle and the capture of HMS Cyane, HMS Levant and HMS Penguin, the final engagements between British and U.S. forces, the Marines had gained a reputation as expert marksmen, especially in defensive and ship-to-ship actions.^[39] They played a large role in the 1813 defense of Sacket's Harbor, New York and Norfolk and Portsmouth, Virginia,^[40] also taking part in the 1814 defense of Plattsburgh in the Champlain Valley during one of the final British offensives along the Canadian-U.S. border. The Battle of Bladensburg, fought 24 August 1814, was one of the worst days for American arms, though a few units and individuals performed heroic service. Notable among them were Commodore Joshua Barney's 500 sailors and the 120 marines under Captain Samuel Miller USMC, who inflicted the bulk of British casualties and were the only effective American resistance during the battle. A final desperate Marine counter attack, with the fighting at close quarters, however was not enough; Barney and Miller's forces were overrun. In all of 114 marines, 11 were killed and 16 wounded. During the battle Captain Miller's arm was badly wounded, for his gallant service in action, Miller was brevetted to the rank of Major USMC.^[41]

The Final Stand at Bladensburg, Maryland, 24 August 1814

After the war, the Marine Corps fell into a malaise that ended with the appointment of Archibald Henderson as its fifth commandant in 1820. Under his tenure, the Corps took on expeditionary duties in the Caribbean, the Gulf of Mexico, Key West, West Africa, the Falkland Islands, and Sumatra. Commandant Henderson is credited with thwarting President Jackson's attempts to combine and integrate the Marine Corps with the Army.^[39] Instead, Congress passed the Act for the Better Organization of the Marine Corps in 1834, stipulating that the Corps was part of the Department of the Navy as a sister service to the Navy.^[42] This would be the first of many times that the independent existence of the Corps was challenged.

Commandant Henderson volunteered the Marines for service in the Seminole Wars of 1835, personally leading nearly half of the entire Corps (two battalions) to war. A decade later, in the Mexican–American War (1846–1848), the Marines made their famed assault on Chapultepec Palace in Mexico City, which would be later celebrated as the "Halls of Montezuma" in the Marines' Hymn. In fairness to the U.S. Army, most of the troops who made the final assault at the Halls of Montezuma were soldiers and not marines.^[43] The Americans forces were led by Army General Winfield Scott. Scott organized two storming parties of about 250 men each for 500 men total including 40 marines.

In the 1850s, the Marines engaged in service in Panama and Asia and were attached to Commodore Matthew Perry's East India Squadron on its historic trip to the Far East.^[44]

American Civil War to World War I

The Marine Corps played a small role in the Civil War (1861–1865); their most prominent task was blockade duty. As more and more states seceded from the Union, about a third of the Corps's officers left the United States to join the Confederacy and form the Confederate States Marine Corps, which ultimately played little part in the war. The battalion of recruits formed for the First Battle of Bull Run performed poorly, retreating with the rest of the Union forces.^[31] Blockade duty included sea-based amphibious operations to secure forward bases. In late November 1861, Marines and sailors landed a reconnaissance in force from USS Flag at Tybee Island, Georgia, to occupy the lighthouse and Martello tower on the northern end of the island. It would later be the Army base for bombardment of Fort Pulaski.^[45] In April and May 1862, Marines participated in the capture and occupation of New Orleans and the occupation of Baton Rouge, Louisiana,^[46] key events in the war that helped secure Union control of the lower Mississippi River basin and denied the Confederacy a major port and naval base on the Gulf Coast.

The remainder of the 19th century was marked by declining strength and introspection about the mission of the Marine Corps. The Navy's transition from sail to steam put into question the need for Marines on naval ships. Meanwhile, Marines served as a convenient resource for interventions and landings to protect American interests overseas. The Corps was involved in over 28 separate interventions in the 30 years from the end of the American Civil War to the end of 19th century.^[47] They were called upon to stem political and labor unrest within the United States.^[48] Under Commandant Jacob Zeilin's tenure, Marine customs and traditions took shape: the Corps adopted the Marine Corps emblem on 19 November 1868. It was during this time that "The Marines' Hymn" was first heard. Around 1883, the Marines adopted their current motto "Semper fidelis" (Always Faithful).^[39] John Philip Sousa, the musician and composer, enlisted as a Marine apprentice at age 13, serving from 1867 until 1872, and again from 1880 to 1892 as the leader of the Marine Band.

During the Spanish–American War (1898), Marines led American forces ashore in the Philippines, Cuba, and Puerto Rico, demonstrating their readiness for deployment. At Guantánamo Bay, Cuba, the Marines seized an advanced naval base that remains in use today. Between 1899 and 1916, the Corps continued its record of participation in foreign expeditions, including the Philippine–American War, the Boxer Rebellion in China, Panama, the Cuban Pacifications, the Perdicaris incident in Morocco, Veracruz, Santo Domingo, and the Banana Wars in Haiti and Nicaragua; the experiences gained in counter-insurgency and guerrilla operations during this period were consolidated into the Small Wars Manual.^[49]

World War I

Georges Scott, American Marines in Belleau Wood, 1918

During World War I, Marines served as a part of the American Expeditionary Force under General John J. Pershing when America entered into the war on 6 April 1917. The Marine Corps had a deep pool of officers and non-commissioned officers with battle experience and thus experienced a large expansion. The U.S. Marine Corps entered the war with 511 officers and 13,214 enlisted personnel and by 11 November 1918 had reached a strength of 2,400 officers and 70,000 enlisted.^[50] African-Americans were entirely excluded from the Marine Corps during this conflict.^[51] Opha May Johnson was the first woman to enlist in the Marines; she joined the Marine Corps Reserve in 1918 during World War I, officially becoming the first female Marine.^[52] From then until the end of World War I, 305 women enlisted in the Corps.^[53] During the Battle of Belleau Wood in 1918, the Marines and U.S. media reported that Germans had nicknamed them Teufel Hunden, meaning "Devil Dogs" for their reputation as shock troops and marksmen at ranges up to 900 meters; there is no evidence of this in German records (as Teufelshunde would be the proper German phrase). Nevertheless, the name stuck in U.S. Marine lore.^[54]

Between the World Wars, the Marine Corps was headed by Commandant John A. Lejeune, and under his leadership, the Corps studied and developed amphibious techniques that would be of great use in World War II. Many officers, including Lieutenant Colonel Earl Hancock "Pete" Ellis, foresaw a war in the Pacific with Japan and undertook preparations for such a conflict. Through 1941, as the prospect of war grew, the Corps pushed urgently for joint amphibious exercises with the Army and acquired amphibious equipment that would prove of great use in the upcoming conflict.^[55]

World War II

Former French Foreign Legion Lieutenant, and U.S. Marine Corps officer Peter J. Ortiz, who served in the European theater, often behind enemy lines

In World War II, the Marines performed a central role in the Pacific War, along with the U.S. Army. The battles of Guadalcanal, Bougainville, Tarawa, Guam, Tinian, Cape Gloucester, Saipan, Peleliu, Iwo Jima, and Okinawa saw fierce fighting between marines and the Imperial Japanese Army. Some 600,000 Americans served in the U.S. Marine Corps in World War II.^[56]

The Battle of Iwo Jima, which began on 19 February 1945, was arguably the most famous Marine engagement of the war. The Japanese had learned from their defeats in the Marianas Campaign and prepared many fortified positions on the island including pillboxes and network of tunnels. The Japanese put up fierce resistance, but American forces reached the summit of Mount Suribachi on 23 February. The mission was accomplished with high losses of 26,000 American casualties and 22,000 Japanese.^[57]

The Marines played a comparatively minor role in the European theater. Nonetheless, they did continue to provide security detachments to U.S. embassies and ships, contributed personnel to small special ops teams dropped into Nazi-occupied Europe as part of Office of Strategic Services (OSS, the precursor to the CIA) missions, and acted as staff planners and trainers for U.S. Army amphibious operations, including the Normandy landings.^[58][59] By the end of the war, the Corps had expanded from two brigades to six divisions, five air wings, and supporting troops, totaling about 485,000 marines. In addition, 20 defense battalions and a parachute battalion were raised.^[60] Nearly 87,000 marines were casualties during World War II (including nearly 20,000 killed), and 82 were awarded the Medal of Honor.^[61]

In 1942, the Navy Seabees were created with the Marine Corps providing their organization and military training. Many Seabee units were issued the USMC standard issue and were re-designated "Marine". Despite the Corps giving them their military organization, military training, issuing them uniforms and redesignating their units, the Seabees remained Navy.^{[note 2][62][63]} USMC historian Gordon L. Rottmann writes that one of the "Navy's biggest contributions to the Marine Corps during WWII was the creation of the Seabees."^[64]

Despite Secretary of the Navy James Forrestal's prediction that the Marine flag raising at Iwo Jima meant "a Marine Corps for the next five hundred years",^[65][66] the Corps faced an immediate institutional crisis following the war because of a suddenly shrunken budget. Army generals pushing for a strengthened and reorganized defense establishment attempted to fold the Marine mission and assets into the Navy and Army. Drawing on hastily assembled Congressional support, and with the assistance of the so-called "Revolt of the Admirals", the Marine Corps rebuffed such efforts to dismantle the Corps, resulting in statutory protection of the Marine Corps in the National Security Act of 1947.^[67] Shortly afterward, in 1952 the Douglas–Mansfield Act afforded the commandant an equal voice with the Joint Chiefs of Staff on matters relating to the Marines and established the structure of three active divisions and air wings that remain today.

Korean War

The beginning of the Korean War (1950–1953) saw the hastily formed Provisional Marine Brigade holding the defensive line at the Pusan Perimeter. To execute a flanking maneuver, General Douglas MacArthur called on United Nations forces, including U.S. marines, to make an amphibious landing at Inchon. The successful landing resulted in the collapse of North Korean lines and the pursuit of North Korean forces north near the Yalu River until the entrance of the People's Republic of China into the war. Chinese troops surrounded, surprised, and overwhelmed the overextended and outnumbered American forces. The U.S. Army's X Corps, which included the 1st Marine Division and the Army's 7th Infantry Division regrouped and inflicted heavy casualties during their fighting withdrawal to the coast, known as the Battle of Chosin Reservoir.

The fighting calmed after the Battle of the Chosin Reservoir, but late in March 1953, the relative quiet of the war was broken when the People's Liberation Army launched a massive offensive on three outposts manned by the 5th Marine Regiment. These outposts were codenamed "Reno", "Vegas", and "Carson". The campaign was collectively known as the Nevada Cities Campaign. There was brutal fighting on Reno hill, which was eventually captured by the Chinese. Although Reno was lost, the 5th Marines held both Vegas and Carson through the rest of the campaign. In this one campaign, the Marines suffered approximately 1,000 casualties and might have suffered much more without the U.S. Army's Task Force Faith. Marines would continue a battle of attrition around the 38th Parallel until the 1953 armistice.^[68] During the war, the Corps expanded from 75,000 regulars to a force of 261,000 marines, mostly reservists; 30,544 marines were killed or wounded during the war, and 42 were awarded the Medal of Honor.^[69]

Vietnam War

The Marine Corps served in the Vietnam War, taking part in such battles as the Battle of Hue and the Battle of Khe Sanh in 1968. Individuals from the USMC generally operated in the Northern I Corps Regions of South Vietnam. While there, they were constantly engaged in a guerrilla war against the Viet Cong, along with an intermittent conventional war against the North Vietnamese Army, this made the Marine Corps known throughout Vietnam and gained a frightening reputation from the Viet Cong. Portions of the Corps were responsible for the less-known Combined Action Program that implemented unconventional techniques for counter-insurgency and worked as military advisers to the Republic of Vietnam Marine Corps. Marines were withdrawn in 1971 and returned briefly in 1975 to evacuate Saigon and attempt a rescue of the crew of the SS Mayaguez.^[70] Vietnam was the longest war up to that time for the Marines; by its end, 13,091 had been killed in action,^[71][72] 51,392 had been wounded, and 57 Medals of Honor had been awarded.^[73][74] Because of policies concerning rotation, more marines were deployed for service during Vietnam than World War II.^[75]

While recovering from Vietnam, the Corps hit a detrimental low point in its service history caused by courts-martial and non-judicial punishments related partially to increased unauthorized absences and desertions during the war. Overhaul of the Corps began in the late 1970s, discharging the most delinquent, and once the quality of new recruits improved, the Corps focused on reforming the non-commissioned officer Corps, a vital functioning part of its forces.^[25]

Interim: Vietnam War to the War on Terror

Beirut Memorial at Marine Corps Base Camp Lejeune

After the Vietnam War, the U.S. Marines resumed their expeditionary role, participating in the failed 1980 Iran hostage rescue attempt Operation Eagle Claw, the Operation Urgent Fury and the Operation Just Cause. On 23 October 1983, the Marine barracks in Beirut was bombed, causing the highest peacetime losses to the Corps in its history (220 marines and 21 other service members were killed) and leading to the American withdrawal from Lebanon. In 1990, marines of the Joint Task Force Sharp Edge saved thousands of lives by evacuating British, French and American nationals from the violence of the Liberian Civil War.

During the Persian Gulf War of 1990 to 1991, Marine task forces formed for Operation Desert Shield and later liberated Kuwait, along with Coalition forces, in Operation Desert Storm.^[39] Marines participated in combat operations in Somalia (1992–1995) during Operations Restore Hope, Restore Hope II, and United Shield to provide humanitarian relief.^[76] In 1997, marines took part in Operation Silver Wake, the evacuation of American citizens from the U.S. Embassy in Tirana, Albania.

Global War on Terrorism

Following the attacks on 11 September 2001, President George W. Bush announced the Global War on Terrorism. The stated objective of the Global War on Terror is "the defeat of Al-Qaeda, other terrorist groups and any nation that supports or harbors terrorists".^[77] Since then, the Marine Corps, alongside the other military services, has engaged in global operations around the world in support of that mission.

In spring 2009, President Barack Obama's goal of reducing spending in the Defense Department was led by Secretary Robert Gates in a series of budget cuts that did not significantly change the Corps's budget and programs, cutting only the VH-71 Kestrel and resetting the VXX program.^[78][79][80] However, the National Commission on Fiscal Responsibility and Reform singled the Corps out for the brunt of a series of recommended cuts in late 2010.^[81] In light of budget sequestration in 2013, General James Amos set a goal of a force of 174,000 Marines.^[82] He testified that this was the minimum number that would allow for an effective response to even a single contingency operation, but it would reduce the peacetime ratio of time at home bases to time deployed down to a historical low level.^[83]

Afghanistan Campaign

Marines and other American forces began staging in Pakistan and Uzbekistan on the border of Afghanistan as early as October 2001 in preparation for Operation Enduring Freedom.^[84] The 15th and 26th Marine Expeditionary Units were some of the first conventional forces into Afghanistan in support of Operation Enduring Freedom in November 2001.^[85]

After that, Marine battalions and squadrons rotated through, engaging Taliban and Al-Qaeda forces. Marines of the 24th Marine Expeditionary Unit flooded into the Taliban-held town of Garmsir in Helmand Province on 29 April 2008, in the first major American operation in the region in years.^[86] In June 2009, 7,000 marines with the 2nd Marine Expeditionary Brigade (2nd MEB) deployed to Afghanistan in an effort to improve security^[87] and began Operation Strike of the Sword the next month. In February 2010, the 2nd MEB launched the largest offensive of the Afghan Campaign since 2001, the Battle of Marjah, to clear the Taliban from their key stronghold in Helmand Province.^[88] After Marjah, marines progressed north up the Helmand River and cleared the towns of Kajahki and Sangin. Marines remained in Helmand Province until 2014.^[89]

Iraq Campaign

U.S. Marines served in the Iraq War, along with its sister services. The I Marine Expeditionary Force, along with the U.S. Army's 3rd Infantry Division, spearheaded the 2003 invasion of Iraq.^[90] The Marines left Iraq in the summer of 2003 but returned in the beginning of 2004. They were given responsibility for the Al Anbar Province, the large desert region to the west of Baghdad. During this occupation, the Marines lead assaults on the city of Fallujah in April (Operation Vigilant Resolve) and November 2004 (Operation Phantom Fury) and saw intense fighting in such places as Ramadi, Al-Qa'im and Hīt.^[91] The service's time in Iraq courted controversy with events such as the Haditha killings and the Hamdania incident.^[92][93] The Anbar Awakening and 2007 surge reduced levels of violence. The Marine Corps officially ended its role in Iraq on 23 January 2010 when it handed over responsibility for Al Anbar Province to the U.S. Army.^[94] Marines returned to Iraq in the summer of 2014 in response to growing violence there.^[95]

Operations in Africa

Throughout the Global War on Terrorism, the U.S. Marines have supported operations in Africa to counter Islamic extremism and piracy in the Red Sea. In late 2002, Combined Joint Task Force – Horn of Africa was stood up at Camp Lemonnier, Djibouti to provide regional security.^[96] Despite transferring overall command to the Navy in 2006, the Marines continued to operate in the Horn of Africa into 2007.^[97]

History of the United States Marine Corps

History of the United States Marine Corps

The history of the United States Marine Corps (USMC) begins with the founding of the Continental Marines on 10 November 1775 to conduct ship-to-ship fighting, provide shipboard security and discipline enforcement, and assist in landing forces. Its mission evolved with changing military doctrine and foreign policy of the United States. Owing to the availability of Marine forces at sea, the United States Marine Corps has served in nearly every conflict in United States history. It attained prominence when its theories and practice of amphibious warfare proved prescient, and ultimately formed a cornerstone of U.S. strategy in the Pacific Theater of World War II. By the early 20th century, the Marine Corps would become one of the dominant theorists and practitioners of amphibious warfare. Its ability to rapidly respond on short notice to expeditionary crises has made and continues to make it an important tool for U.S. foreign policy.

John Adams

John Adams

John Adams was an American statesman, attorney, diplomat, writer, and Founding Father who served as the second president of the United States from 1797 to 1801. Before his presidency, he was a leader of the American Revolution that achieved independence from Great Britain. During the latter part of the war and in the early years of the nation, he served as a diplomat in Europe. He was the first person to hold the office of vice president of the United States, serving from 1789 to 1797. Adams was a dedicated diarist and regularly corresponded with many important contemporaries, including his wife and adviser Abigail Adams as well as his friend and rival Thomas Jefferson.

Continental Marines

Continental Marines

The Continental Marines were the amphibious infantry of the American Colonies during the American Revolutionary War. The Corps was formed by the Continental Congress on November 10, 1775 and was disbanded in 1783. Their mission was multi-purpose, but their most important duty was to serve as onboard security forces, protecting the captain of a ship and his officers. During naval engagements, in addition to manning the cannons along with the crew of the ship, Marine sharpshooters were stationed in the fighting tops of a ship's masts specifically to shoot the opponent's officers, naval gunners, and helmsmen.

American Revolutionary War

American Revolutionary War

The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was the military conflict of the American Revolution in which American Patriot forces under George Washington's command defeated the British, establishing and securing the independence of the United States. Fighting began on April 19, 1775, at the Battles of Lexington and Concord. The war was formalized and intensified following passage of the Lee Resolution on July 2, 1776, which asserted that the Thirteen Colonies were "free and independent states", and the Declaration of Independence, drafted by the Committee of Five and written primarily by Thomas Jefferson, two days later, on July 4, 1776, by the Second Continental Congress in Philadelphia.

Battle of Princeton

Battle of Princeton

The Battle of Princeton was a battle of the American Revolutionary War, fought near Princeton, New Jersey on January 3, 1777, and ending in a small victory for the Colonials. General Lord Cornwallis had left 1,400 British troops under the command of Lieutenant Colonel Charles Mawhood in Princeton. Following a surprise attack at Trenton early in the morning of December 26, 1776, General George Washington of the Continental Army decided to attack the British in New Jersey before entering the winter quarters. On December 30, he crossed the Delaware River back into New Jersey. His troops followed on January 3, 1777. Washington advanced to Princeton by a back road, where he pushed back a smaller British force but had to retreat before Cornwallis arrived with reinforcements. The battles of Trenton and Princeton were a boost to the morale of the patriot cause, leading many recruits to join the Continental Army in the spring.

Continental Army

Continental Army

The Continental Army was the army of the United Colonies representing the Thirteen Colonies and later the United States during the American Revolutionary War. It was formed on June 14, 1775 by a resolution passed by the Second Continental Congress, meeting in Philadelphia after the war's outbreak. The Continental Army was created to coordinate military efforts of the colonies in the war against the British, who sought to maintain control over the American colonies. General George Washington was appointed commander-in-chief of the Continental Army and maintained this position throughout the war.

Continental Navy

Continental Navy

The Continental Navy was the navy of the Thirteen Colonies during the American Revolutionary War. Founded on October 13, 1775, the fleet developed into a relatively substantial force throughout the Revolutionary War, owing partially to the substantial efforts of the Continental Navy's patrons within the Continental Congress. These Congressional Patrons included the likes of John Adams, who served as the Chairman of the Naval Committee until 1776, when Commodore Esek Hopkins received instruction from the Continental Congress to assume command of the force.

French First Republic

French First Republic

In the history of France, the First Republic, sometimes referred to in historiography as Revolutionary France, and officially the French Republic, was founded on 21 September 1792 during the French Revolution. The First Republic lasted until the declaration of the First Empire on 18 May 1804 under Napoléon Bonaparte, although the form of the government changed several times.

Department of the Navy

The Department of the Navy, led by the Secretary of the Navy, is a military department of the cabinet-level U.S. Department of Defense that oversees the Marine Corps and the Navy. The most senior Marine officer is the Commandant (unless a Marine officer is the Chairman of the Joint Chiefs or Vice Chairman of the Joint Chiefs), responsible to the Secretary of the Navy for organizing, recruiting, training, and equipping the Marine Corps so that its forces are ready for deployment under the operational command of the combatant commanders. The Marine Corps is organized into four principal subdivisions: Headquarters Marine Corps (HQMC), the Operating Forces, the Supporting Establishment, and the Marine Forces Reserve (MARFORRES or USMCR).

Headquarters Marine Corps

Headquarters Marine Corps (HQMC) consists of the Commandant of the Marine Corps, the Assistant Commandant of the Marine Corps, the Director Marine Corps Staff, the several Deputy Commandants, the Sergeant Major of the Marine Corps, and various special staff officers and Marine Corps agency heads that report directly to either the Commandant or Assistant Commandant. HQMC is supported by the Headquarters and Service Battalion, USMC providing administrative, supply, logistics, training, and services support to the Commandant and his staff.

Operating Forces

The Operating Forces are divided into three categories: Marine Corps Forces (MARFOR) assigned to unified combatant commands, namely, the Fleet Marine Forces (FMF); Security Forces guarding high-risk naval installations; and Security Guard detachments at American embassies. Under the "Forces for Unified Commands" memo, in accordance with the Unified Command Plan, Marine Corps Forces are assigned to each of the combatant commands at the discretion of the secretary of defense. Since 1991, the Marine Corps has maintained component headquarters at each of the regional unified combatant commands.^[98]

Marine Corps Forces are divided into Forces Command (MARFORCOM) and Pacific Command (MARFORPAC), each headed by a lieutenant general dual-posted as the commanding general of either FMF Atlantic (FMFLANT) or FMF Pacific (FMFPAC), respectively. MARFORCOM/FMFLANT has operational control of the II Marine Expeditionary Force; MARFORPAC/FMFPAC has operational control of the I Marine Expeditionary Force and III Marine Expeditionary Force.^[31]

Marine Air-Ground Task Force

The basic framework for deployable Marine units is the Marine Air-Ground Task Force (MAGTF), a flexible structure of varying size. A MAGTF integrates a ground combat element (GCE), an aviation combat element (ACE), and a logistics combat element (LCE) under a common command element (CE), capable of operating independently or as part of a larger coalition. The MAGTF structure reflects a strong preference in the Corps towards self-sufficiency and a commitment to combined arms, both essential assets to an expeditionary force. The Marine Corps has a wariness and distrust of reliance on its sister services and towards joint operations in general.^[25]

Supporting Establishment

The Supporting Establishment includes the Combat Development Command, the Logistics Command, the Systems Command, the Recruiting Command, the Installations Command, the Marine Band, and the Marine Drum and Bugle Corps.

Marine Corps bases and stations

The Marine Corps operates many major bases, 14 of which host operating forces, 7 support and training installations, as well as satellite facilities.^[99] Marine Corps bases are concentrated around the locations of the Marine Expeditionary Forces, though reserve units are scattered throughout the United States. The principal bases are Camp Pendleton on the West Coast, home to I Marine Expeditionary Force; Camp Lejeune on the East Coast, home to II Marine Expeditionary Force; and Camp Butler in Okinawa, Japan, home to III Marine Expeditionary Force.

Other important bases include air stations, recruit depots, logistics bases, and training commands. Marine Corps Air Ground Combat Center Twentynine Palms in California is the Marine Corps's largest base and home to the Corps's most complex, combined-arms, live-fire training. Marine Corps Base Quantico in Virginia is home to Marine Corps Combat Development Command and nicknamed the "Crossroads of the Marine Corps".^[100][101] The Marine Corps maintains a significant presence in the National Capital Region, with Headquarters Marine Corps scattered amongst the Pentagon, Henderson Hall, Washington Navy Yard, and Marine Barracks, Washington, D.C. Additionally, Marines operate detachments at many installations owned by other branches to better share resources, such as specialty schools. Marines are also present at and operate many forward bases during expeditionary operations.

Marine Forces Reserve

Marine Forces Reserve (MARFORRES/USMCR) consists of the Force Headquarters Group, 4th Marine Division, 4th Marine Aircraft Wing, and the 4th Marine Logistics Group. The MARFORRES/USMCR is capable of forming a 4th Marine Expeditionary Force or reinforcing/augmenting active-duty forces.

There are currently 11 unified combatant commands and each is established as the highest echelon of military commands, in order to provide effective command and control of all U.S. military forces, regardless of branch of service, during peace or during war time. Unified combatant commands are organized either on a geographical basis or on a functional basis, e.g. special operations, force projection, transport, and cybersecurity. Currently, seven combatant commands are designated as geographical, and four are designated as functional. Unified combatant commands are "joint" commands and have specific badges denoting their affiliation.

Additionally, all deployed MEUs are certified as "special operations capable", namely, "MEU(SOC)".

Although the notion of a Marine special operations forces contribution to the United States Special Operations Command (USSOCOM) was considered as early as the founding of USSOCOM in the 1980s, it was resisted by the Marine Corps. Commandant Paul X. Kelley expressed the belief that marines should only support marines and that the Corps should not fund a special operations capability that would not directly support Marine Corps operations.^[102] However, much of the resistance from within the Corps dissipated when Marine leaders watched the Corps' 15th and 26th MEU(SOC)s "sit on the sidelines" during the very early stages of Operation Enduring Freedom while other conventional units and special operations units from the Army, Navy, and Air Force actively engaged in operations in Afghanistan.^[103] After a three-year development period, the Corps agreed in 2006 to supply a 2,500-strong unit, Marine Forces Special Operations Command, which would answer directly to USSOCOM.^[104]

For the 60 female recruits, scheduled to begin training in San Diego in February 2021, the Corps will transfer female drill instructors from their recruit depot in Parris Island, which already has a coed program.^[113] Fifty-three of these recruits successfully graduated from boot camp in April 2021 and became marines.^[114][115]

Minorities

Howard P. Perry, the first Negro recruit in the U.S. Marine Corps, 1942.

In 1776 and 1777, a dozen African American marines served in the American Revolutionary War, but from 1798 to 1942, the Marine Corps followed a racially discriminatory policy of denying African Americans the opportunity to serve.^[116] The Marine Corps was the last of the services to recruit African Americans, and its own history page acknowledges that it was a presidential order that "forced the Corps, despite objections from its leadership, to begin recruiting African American Marines in 1942.^[117].It accepted them as recruits into segregated all-black units.^[116] For the next few decades, the incorporation of black troops was not widely accepted within the Corps, nor was desegregation smoothly or quickly achieved. The integration of non-white Marine Corps personnel proceeded in stages from segregated battalions in 1942, to unified training in 1949, and finally full integration in 1960.^[118]

Today the Marine Corps is a desegregated force, made up of marines of all races working and fighting alongside each other. As of 2020, African Americans are currently underrepresented in the Marine Corps as compared to their overall percentage of the U.S. population. Concurrently, the Marine Corps is the only service where Hispanics are overrepresented per the same metric.^[119]

Rank structure

As in the rest of the United States Armed Forces (excluding the Air Force and Space Force, which do not currently appoint warrant officers), Marine Corps ranks fall into one of three categories: commissioned officer, warrant officer, and enlisted, in decreasing order of authority. To standardize compensation, each rank is assigned a pay grade.^[120]

Commissioned officers

Commissioned officers are distinguished from other officers by their commission, which is the formal written authority, issued in the name of the President of the United States, that confers the rank and authority of a Marine officer. Commissioned officers carry the "special trust and confidence" of the President of the United States.^[17] Marine Corps commissioned officers are promoted based on an "up or out" system in accordance with the Defense Officer Personnel Management Act of 1980.^[121]

Enlisted

Enlisted marines in the pay grades E-1 to E-3 make up the bulk of the Corps's ranks. Although they do not technically hold leadership ranks, the Corps's ethos stresses leadership among all marines, and junior marines are often assigned responsibility normally reserved for superiors. Those in the pay grades of E-4 and E-5 are non-commissioned officers (NCOs).^[122] They primarily supervise junior Marines and act as a vital link with the higher command structure, ensuring that orders are carried out correctly. Marines E-6 and higher are staff non-commissioned officers (SNCOs), charged with supervising NCOs and acting as enlisted advisers to the command.^[123]

The E-8 and E-9 levels have two and three ranks per pay grade, respectively, each with different responsibilities. The first sergeant and sergeant major ranks are command-oriented, serving as the senior enlisted marines in a unit, charged to assist the commanding officer in matters of discipline, administration, and the morale and welfare of the unit. Master sergeants and master gunnery sergeants provide technical leadership as occupational specialists in their specific MOS. The Sergeant Major of the Marine Corps also E-9, is a billet conferred on the senior enlisted marine of the entire Marine Corps, personally selected by the commandant. It is possible for an enlisted marine to hold a position senior to Sergeant Major of the Marine Corps which was the case from 2011 to 2015 with the appointment of Sergeant Major Bryan B. Battaglia to the billet of Senior Enlisted Advisor to the Chairman, who is the most senior enlisted member of the United States military, serving in the Joint Chiefs of Staff.^[124]

Military Occupational Specialty

The Military Occupational Specialty (MOS) is a system of job classification. Using a four digit code, it designates what field and specific occupation a Marine performs. Segregated between officer and enlisted, the MOS determines the staffing of a unit. Some MOSs change with rank to reflect supervisory positions; others are secondary and represent a temporary assignment outside of a Marine's normal duties or special skill.

Initial training

Every year, over 2,000 new Marine officers are commissioned, and 38,000 recruits are accepted and trained.^[31] All new marines, enlisted or officer, are recruited by the Marine Corps Recruiting Command.^[125]

Marine recruits at Marine Corps Recruit Depot San Diego

Commissioned officers are commissioned mainly through one of three sources: Naval Reserve Officer Training Corps, Officer Candidates School, or the United States Naval Academy. Following commissioning, all Marine commissioned officers, regardless of accession route or further training requirements, attend The Basic School at Marine Corps Base Quantico. At The Basic School, second lieutenants, warrant officers, and selected foreign officers learn the art of infantry and combined arms warfare.^[17]

Enlisted marines attend recruit training, known as boot camp, at either Marine Corps Recruit Depot San Diego or Marine Corps Recruit Depot Parris Island. Historically, the Mississippi River served as a dividing line that delineated who would be trained where, while more recently, a district system has ensured a more even distribution of male recruits between the two facilities. All recruits must pass a fitness test to start training; those who fail will receive individualized attention and training until the minimum standards are reached.^[126] Marine recruit training is the longest among the American military services; it is 13 weeks long including processing and out-processing.^[127]

U.S. marines in training

Following recruit training, enlisted marines then attend The School of Infantry at Camp Geiger or Camp Pendleton. Infantry marines begin their combat training, which varies in length, immediately with the Infantry Training Battalion. Marines in all other MOSs train for 29 days in Marine Combat Training, learning common infantry skills, before continuing on to their MOS schools, which vary in length.^[128]

Staff (military)

Staff (military)

A military staff or general staff is a group of officers, enlisted and civilian staff who serve the commander of a division or other large military unit in their command and control role through planning, analysis, and information gathering, as well as by relaying, coordinating, and supervising the execution of their plans and orders, especially in case of multiple simultaneous and rapidly changing complex operations. They are organised into functional groups such as administration, logistics, operations, intelligence, training, etc. They provide multi-directional flow of information between a commanding officer, subordinate military units and other stakeholders. A centralised general staff results in tighter top-down control but requires larger staff at headquarters (HQ) and reduces accuracy of orientation of field operations, whereas a decentralised general staff results in enhanced situational focus, personal initiative, speed of localised action, OODA loop, and improved accuracy of orientation.

Opha May Johnson

Opha May Johnson

Opha May Johnson was the first woman known to have enlisted in the United States Marine Corps. She joined the Marine Corps Reserve on August 13, 1918, officially becoming the first female Marine.

An illustration of U.S. marines in various uniform setups. From left to right: A U.S. marine in a Marine Corps Combat Utility Uniform with full combat load circa 2003, a U.S. marine in a (full) blue dress uniform, a U.S. Marine officer in a service uniform, and a U.S. Marine general in an evening dress uniform.

The Marine Corps has the most stable and most recognizable uniforms in the American military; the Dress Blues dates back to the early 19th century^[31] and the service uniform to the early 20th century. Only a handful of skills (parachutist, air crew, explosive ordnance disposal, etc.) warrant distinguishing badges, and rank insignia is not worn on uniform headgear (with the exception of an officer's garrison service cover).

Marines have four main uniforms: dress, service, utility, and physical training. These uniforms have a few minor but very distinct variations from enlisted personnel to commissioned and non-commissioned officers. The Marine Corps dress uniform is the most elaborate, worn for formal or ceremonial occasions. There are four different forms of the dress uniform. The variations of the dress uniforms are known as "Alphas", "Bravos", "Charlies", or "Deltas". The most common being the "Blue Dress Alphas or Bravos", called "Dress Blues" or simply "Blues". It is most often seen in recruiting advertisements and is equivalent to black tie. There is a "Blue-White" Dress for summer, and Evening Dress for formal (white tie) occasions, which are reserved for SNCO's and officers. Versions with a khaki shirt in lieu of the coat (Blue Dress Charlie/Delta) are worn as a daily working uniform by Marine recruiters and NROTC staff.^[129]

The service uniform was once the prescribed daily work attire in garrison; however, it has been largely superseded in this role by the utility uniform. Consisting of olive green and khaki colors. It is roughly equivalent in function and composition to a business suit.^[129]

The utility uniform, currently the Marine Corps Combat Utility Uniform, is a camouflage uniform intended for wear in the field or for dirty work in garrison, though it has been standardized for regular duty. It is rendered in MARPAT pixelated camouflage that breaks up the wearer's shape. In garrison, the woodland and desert uniforms are worn depending on the marine's duty station.^[130] Marines consider the utilities a working uniform and do not permit their wear off-base, except in transit to and from their place of duty and in the event of an emergency.^[129]

Full dress uniform

Full dress uniform

Full dress uniform, also known as a ceremonial dress uniform or parade dress uniform, is the most formal type of uniforms used by military, police, fire and other public uniformed services for official parades, ceremonies, and receptions, including private ones such as marriages and funerals. Full dress uniforms typically include full-size orders and medals insignia. Styles tend to trace back to uniforms used during the 19th century, although the 20th century saw the adoption of mess dress-styled full-dress uniforms. Designs may depend on regiment or service branch. In Western dress codes, full dress uniform is a permitted supplementary alternative equivalent to the civilian white tie for evening wear or morning dress for day wear – sometimes collectively called full dress – although military uniforms are the same for day and evening wear. As such, full dress uniform is the most formal uniform, followed by the mess dress uniform.

Mess dress uniform

Mess dress uniform

Mess dress uniform is the most formal type of uniforms used by military personnel, police personnel, and other uniformed services members. It frequently consists of a mess jacket, trousers, white dress shirt and a black bow tie, along with orders and medals insignia. Design may depend on regiment or service branch, e.g. army, navy, air force, marines, etc. In Western dress codes, mess dress uniform is the supplementary alternative equivalent to the civilian black tie for evening wear or black lounge suit for day wear although military uniforms are the same for day and evening wear. Mess dress uniforms are typically less formal than full dress uniform, but more formal than service dress uniform.

Insignia and badges of the United States Marine Corps are military "badges" issued by the United States Department of the Navy to Marines who achieve certain qualifications and accomplishments while serving on both active and reserve duty in the United States Marine Corps.

Black tie

Black tie

Black tie is a semi-formal Western dress code for evening events, originating in British and American conventions for attire in the 19th century. In British English, the dress code is often referred to synecdochically by its principal element for men, the dinner suit or dinner jacket. In American English, the equivalent term tuxedo is common. The dinner suit is a black, midnight blue or white two- or three-piece suit, distinguished by satin or grosgrain jacket lapels and similar stripes along the outseam of the trousers. It is worn with a white dress shirt with standing or turndown collar and link cuffs, a black bow tie, typically an evening waistcoat or a cummerbund, and black patent leather dress shoes or court pumps. Accessories may include a semi-formal homburg, bowler, or boater hat. For women, an evening gown or other fashionable evening attire may be worn.

White tie

White tie

White tie, also called full evening dress or a dress suit, is the most formal in traditional evening western dress codes. For men, it consists of a black tail coat worn over a white dress shirt with a starched or pique bib, white piqué waistcoat and the eponymous white bow tie worn around a standing wing collar. Mid or high-waisted black trousers with galon, a braid of trim consisting of two silk stripes to conceal the outer seams of the trousers, along with court shoes complete the outfit. Orders, decorations and medals may be worn. Acceptable accessories include a black top hat, white gloves, a white scarf, a pocket watch, a white pocket square, and a boutonnière. Women wear full-length ball or evening gowns with evening gloves and, optionally, tiaras, jewellery, and a small handbag.

MARPAT

MARPAT

MARPAT is a multi-scale camouflage pattern in use with the United States Marine Corps, designed in 2001 and introduced from late 2002 to early 2005 with the Marine Corps Combat Utility Uniform (MCCUU), which replaced the Camouflage Utility Uniform. Its design and concept are based on the Canadian CADPAT pattern. The pattern is formed of small rectangular pixels of color. In theory, it is a far more effective camouflage than standard uniform patterns because it mimics the dappled textures and rough boundaries found in natural settings. It is also known as the "digital pattern" or "digi-cammies" because of its micropattern (pixels) rather than the old macropattern.

Camouflage

Camouflage

Camouflage is the use of any combination of materials, coloration, or illumination for concealment, either by making animals or objects hard to see, or by disguising them as something else. Examples include the leopard's spotted coat, the battledress of a modern soldier, and the leaf-mimic katydid's wings. A third approach, motion dazzle, confuses the observer with a conspicuous pattern, making the object visible but momentarily harder to locate, as well as making general aiming easier. The majority of camouflage methods aim for crypsis, often through a general resemblance to the background, high contrast disruptive coloration, eliminating shadow, and countershading. In the open ocean, where there is no background, the principal methods of camouflage are transparency, silvering, and countershading, while the ability to produce light is among other things used for counter-illumination on the undersides of cephalopods such as squid. Some animals, such as chameleons and octopuses, are capable of actively changing their skin pattern and colours, whether for camouflage or for signalling. It is possible that some plants use camouflage to evade being eaten by herbivores.

Official traditions and customs

As in any military organization, the official and unofficial traditions of the Marine Corps serve to reinforce camaraderie and set the service apart from others. The Corps's embrace of its rich culture and history is cited as a reason for its high esprit de corps.^[17] An important part of the Marine Corps culture is the traditional seafaring naval terminology derived from its history with the Navy. "Marines" are not "soldiers" or "sailors".^[131]

The Eagle, Globe and Anchor along with the U.S. flag, the Marine Corps flag and the Commandant's flag

The Marine Corps emblem is the Eagle, Globe, and Anchor, sometimes abbreviated "EGA", adopted in 1868.^[132] The Marine Corps seal includes the emblem, also is found on the flag of the United States Marine Corps, and establishes scarlet and gold as the official colors.^[133] The Marine motto Semper Fidelis means Always Faithful in Latin, often appearing as Semper Fi. The Marines' Hymn dates back to the 19th century and is the oldest official song in the United States armed forces. Semper Fi is also the name of the official march of the Corps, composed by John Philip Sousa. The mottos "Fortitudine" (With Fortitude); By Sea and by Land, a translation of the Royal Marines' Per Mare, Per Terram; and To the Shores of Tripoli were used until 1868.^[134]

Two styles of swords are worn by marines: the officers' Mameluke Sword, similar to the Persian shamshir presented to Lt. Presley O'Bannon after the Battle of Derna, and the Marine NCO sword.^[31] The Marine Corps Birthday is celebrated every year on 10 November in a cake-cutting ceremony where the first slice of cake is given to the oldest marine present, who in turn hands it off to the youngest marine present. The celebration includes a reading of Commandant Lejeune's Birthday Message.^[135] Close Order Drill is heavily emphasized early on in a marine's initial training, incorporated into most formal events, and is used to teach discipline by instilling habits of precision and automatic response to orders, increase the confidence of junior officers and noncommissioned officers through the exercise of command and give marines an opportunity to handle individual weapons.^[136]

Unofficial traditions and customs

A recruiting poster making use of the "Teufel Hunden" [sic] nickname

Marines have several generic nicknames:

• Devil Dog: German soldiers during the First World War said that at Belleau Wood the marines were so vicious that the German infantrymen called them Teufel Hunden – 'devil dogs'.^{[137][138][139][140]}
• Gyrene: commonly used between fellow marines.^[141]
• Leatherneck: refers to a leather collar formerly part of the Marine uniform during the Revolutionary War period.^[142]
• Jarhead has several oft-disputed explanations.^[143]

Some other unofficial traditions include mottos and exclamations:

• Oorah is common among marines, being similar in function and purpose to the Army, Air Force, and Space Force's hooah and the Navy's hooyah cries. Many possible etymologies have been offered for the term.^[144]
• Semper Fi is a common greeting among serving and veteran marines.
• Improvise, Adapt and Overcome has become an adopted mantra in many units.^[145]

The Marines have historically had issues with extremism in their ranks, particularly White supremacy. In 1976 the Camp Pendleton Chapter of the Ku Klux Klan had over 100 members and was headed by an active duty marine. In 1986, a number of marines were implicated in the theft of weapons for the White Patriot Party. The USMC, along with the rest of the military, has since made a serious effort to address extremism in the ranks.^[146]

Veteran marines

The Corps encourages the idea that "marine" is an earned title, and most Marine Corps personnel take to heart the phrase, "Once a marine, Always a marine". They reject the term "ex-marine" in most circumstances. There are no regulations concerning the address of persons who have left active service, so a number of customary terms have come into common use.^[67]

Martial arts program

Marines training in martial arts

In 2001, the Marine Corps initiated an internally designed martial arts program, called Marine Corps Martial Arts Program (MCMAP). Because of an expectation that urban and police-type peacekeeping missions would become more common in the 21st century, placing marines in even closer contact with unarmed civilians, MCMAP was implemented to provide marines with a larger and more versatile set of less-than-lethal options for controlling hostile, unarmed individuals. It is a stated aim of the program to instill and maintain the "Warrior Ethos" within marines.^[147] The MCMAP is an eclectic mix of different styles of martial arts melded together. MCMAP consists of punches and kicks from Taekwondo and Karate, opponent weight transfer from Jujitsu, ground grappling involving joint locking techniques and chokes from Brazilian jiu-jitsu, and a mix of knife and baton/stick fighting derived from Eskrima, and elbow strikes and kick boxing from Muay Thai. Marines begin MCMAP training in boot camp, where they will earn the first of five available belts. The belts begin at tan and progress to black and are worn with standard utility uniforms.^[148]

The Eagle, Globe, and Anchor is the official emblem and insignia of the United States Marine Corps. The current emblem traces its roots in the designs and ornaments of the early Continental Marines as well as the United Kingdom's Royal Marines. The present emblem, adopted in 1955, differs from the emblem of 1868 only by a change in the eagle. Before that time many devices, ornaments, ribbons, and distinguishing marks followed one another as official badges of the corps.

Latin

Latin

Latin is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars supplanted it in common academic and political usage. For most of the time it was used, it would be considered a "dead language" in the modern linguistic definition; that is, it lacked native speakers, despite being used extensively and actively.

Marines' Hymn

Marines' Hymn

The "Marines' Hymn" is the official hymn of the United States Marine Corps, introduced by the first director of the USMC Band, Francesco Maria Scala. Its music originates from an 1867 work by Jacques Offenbach with the lyrics added by an anonymous author at an unknown time in the following years. Authorized by the Commandant of the Marine Corps in 1929, it is the oldest official song in the United States Armed Forces. The "Marines' Hymn" is typically sung at the position of attention as a gesture of respect. However, the third verse is also used as a toast during formal events, such as the birthday ball and other ceremonies.

Semper Fidelis (march)

Semper Fidelis (march)

"Semper Fidelis", written in 1888 by John Philip Sousa, is regarded as the official march of the United States Marine Corps. This piece was one of two composed in response to a request from United States President Chester A. Arthur for a new piece to be associated with the United States President. The words semper fidelis are Latin for "always faithful." The piece was created for a wind band in addition to a percussion section. There is a very prominent drum solo in the middle of the piece which includes a skillful dynamic change. It features staccato notes and sharp tonguing.

The basic infantry weapon of the Marine Corps has been the M16A4 service rifle. Most non-infantry marines have been equipped with the M4 Carbine^[150] or Colt 9mm SMG.^[151] The standard side arm is the M9A1 pistol. The Colt M1911 is also being put back into service as the M45A1 Close Quarter Battle Pistol (CQBP) in small numbers. Suppressive fire is provided by the M27 IAR, M249 SAW, and M240 machine guns, at the squad and company levels respectively. In 2018, the M27 IAR was selected to be the standard issue rifle for the all infantry squads.^[152] In 2021, the Marine Corps committed to fielding suppressors to all its infantry units, making it the first branch of the U.S. military to adopt them for widespread use.^[153]

Indirect fire is provided by the M203 grenade launcher and the M32 grenade launcher in fireteams, M224 60 mm mortar in companies, and M252 81 mm mortar in battalions. The M2 .50 caliber heavy machine gun and MK19 automatic grenade launcher (40 mm) are available for use by dismounted infantry, though they are more commonly vehicle-mounted. Precision firepower is provided by the M40 series and the Barrett M107, while designated marksmen use the DMR (being replaced by the M39 EMR), and the SAM-R.^[154]

The Marine Corps utilizes a variety of direct-fire rockets and missiles to provide infantry with an offensive and defensive anti-armor capability. The SMAW and AT4 are unguided rockets that can destroy armor and fixed defenses (e.g., bunkers) at ranges up to 500 meters. The smaller and lighter M72 LAW can destroy targets at ranges up to 200 meters.^[155][156] The Predator SRAW, FGM-148 Javelin and BGM-71 TOW are anti-tank guided missiles. The Javelin can utilize top-attack profiles to avoid heavy frontal armor. The Predator is a short-range fire-and-forget weapon; the Javelin and TOW are heavier missiles effective past 2,000 meters that give infantry an offensive capability against armor.^[157]

Ground vehicles

The Corps operates the same HMMWV as does the Army, which is in the process of being replaced by the Joint Light Tactical Vehicle (JLTV). However, for its specific needs, the Corps uses a number of unique vehicles. The LAV-25 is a dedicated wheeled armored personnel carrier, similar to the Army's Stryker vehicle, used to provide strategic mobility.^[158] Amphibious capability is provided by the AAV-7A1 Assault Amphibious Vehicle, an armored tracked vehicle that doubles as an armored personnel carrier, due to be replaced by the Amphibious Combat Vehicle, a faster vehicle with superior armor and weaponry. The threat of land mines and improvised explosive devices in Iraq and Afghanistan has seen the Corps begin purchasing heavy armored vehicles that can better withstand the effects of these weapons as part of the Mine Resistant Ambush Protected vehicle program.^[159][160]

The Marines also operate the M777 155 mm howitzer and the High Mobility Artillery Rocket System (HIMARS), a truck-mounted rocket artillery system. Both are capable of firing guided munitions.^[161] In 2020, the Marine Corps retired its M1A1 Abrams tanks and eliminated all of its tank units. General David Berger explained the decision describing the long-serving Marine weapons system as "operationally unsuitable for our highest-priority challenges." The move leaves the Army as the sole operator of American tanks.^[162]

Aircraft

The organic aviation capability of the Marine Corps is essential to its amphibious mission. Marine Corps Aviation operates both rotary-wing and fixed-wing aircraft mainly to provide Assault Support and close air support to its ground forces. Other aircraft types are used in a variety of support and special-purpose roles. The light transport and attack capabilities are provided by the Bell UH-1Y Venom and Bell AH-1Z Viper.^[163] Medium-lift squadrons utilize the MV-22 Osprey tiltrotor. Heavy-lift squadrons are equipped with the CH-53E Super Stallion helicopter, which are being replaced with the upgraded CH-53K.^[164]

Marine attack squadrons fly the AV-8B Harrier II; while the fighter/attack mission is handled by the single-seat and dual-seat versions of the F/A-18 Hornet strike-fighter aircraft. The AV-8B is a V/STOL aircraft that can operate from amphibious assault ships, land air bases and short, expeditionary airfields, while the F/A-18 can only be flown from land or aircraft carriers. Both are slated to be replaced by 340 of the STOVL B version of the F-35 Lightning II^[165] and 80 of the carrier F-35C versions for deployment with Navy carrier air wings.^{[166][167][168][169]}

The Corps operates its own organic aerial refueling assets in the form of the KC-130 Hercules; however it also receives a large amount of support from the U.S. Air Force. The Hercules doubles as a ground refueler and tactical-airlift transport aircraft. The USMC electronic warfare plane, the EA-6B, was retired in 2019. The Marines operate unmanned aerial vehicles: the RQ-7 Shadow and Scan Eagle for tactical reconnaissance.^[170]

Marine Fighter Training Squadron 401 (VMFT-401), operates F-5E, F-5F and F-5N Tiger II aircraft in support of air combat adversary (aggressor) training. Marine Helicopter Squadron One (HMX-1) operates the VH-3D Sea King and VH-60N Whitehawk helicopters in the VIP transport role, most notably Marine One, but are due to be replaced. A single Marine Corps C-130 Hercules aircraft, "Fat Albert", is used to support the U.S. Navy's flight demonstration team, the "Blue Angels".^[171]

The M1911 is a single-action, recoil-operated, semi-automatic pistol chambered for the .45 ACP cartridge. The pistol's formal U.S. military designation as of 1940 was Automatic Pistol, Caliber .45, M1911 for the original model adopted in March 1911, and Automatic Pistol, Caliber .45, M1911A1 for the improved M1911A1 model which entered service in 1926. The designation changed to Pistol, Caliber .45, Automatic, M1911A1 in the Vietnam War era.

M27 Infantry Automatic Rifle

M27 Infantry Automatic Rifle

The M27 Infantry Automatic Rifle (IAR) is a 5.56mm select-fire assault rifle, based on the HK416 by Heckler & Koch. It is used by the United States Marine Corps (USMC) and is intended to be issued to all infantry riflemen as well as automatic riflemen. The USMC initially planned to purchase 6,500 M27s to replace a portion of the M249 light machine guns employed by automatic riflemen within Infantry and Light Armored Reconnaissance Battalions. Approximately 8,000–10,000 M249s will remain in service with the Marine Corps to be used at the discretion of company commanders. In December 2017, the Marine Corps announced that it would equip every member of an infantry squad with the M27, replacing the current M4 carbines and M16A4 rifles.

M249 light machine gun

M249 light machine gun

The M249 light machine gun (LMG), also known as the M249 Squad Automatic Weapon (SAW), which continues to be the manufacturer's designation, and formally written as Light Machine Gun, 5.56 mm, M249, is the American adaptation of the Belgian FN Minimi, a light machine gun manufactured by the Belgian company FN Herstal (FN).

M203 grenade launcher

M203 grenade launcher

The M203 is a single-shot 40 mm under-barrel grenade launcher designed to attach to a rifle. It uses the same rounds as the older stand-alone M79 break-action grenade launcher, which utilizes the high-low propulsion system to keep recoil forces low. Quite versatile and compatible with many rifle models, the M203 was originally designed for the U.S. M16 and its carbine variant, the M4. The launcher can also be mounted onto a C7, a Canadian version of the M16 rifle; however, this requires the prior removal of the bottom handguard.

M224 mortar

M224 mortar

The M224 60 mm Lightweight Company Mortar System (LWCMS) is a smooth bore, muzzle-loading, high-angle-of-fire mortar used for close-in support of ground troops. It was deployed extensively in the War in Afghanistan by the United States military.

In general, the Marine Corps shares many resources with the other branches of the United States Armed Forces. However, the Corps has consistently sought to maintain its own identity with regard to mission, funding, and assets, while utilizing support available from the larger branches. While the Marine Corps has far fewer installations both in the U.S. and worldwide than the other branches, many Army posts, Naval stations, and Air Force bases have a Marine presence. They also cross-train with other countries.

Assault Amphibious Vehicles approaching the well deck of USS Bonhomme Richard

The Marine Corps's counterpart under the Department of the Navy is the United States Navy. As a result, the Navy and Marine Corps have a close relationship, more so than with other branches of the military. Whitepapers and promotional literature have commonly used the phrase "Navy-Marine Corps Team",^[172][173] or refer to "the Naval Service". Both the Chief of Naval Operations (CNO) and Commandant of the Marine Corps report directly to the Secretary of the Navy.

Operationally, the Marine Corps provides the Fleet Marine Forces for service with the Navy's fleets, including the forward-deployed Marine Expeditionary Units embarked aboard Navy amphibious warships. The Corps also contributes some Marine Aviation fixed-wing fighter/attack assets (aircraft squadrons and related aircraft maintenance augmentation units) as part of the Carrier Air Wings deployed aboard aircraft carriers. The Marine Corps Security Force Regiment provides infantry-based security battalions and Fleet Anti-terrorism Security Team companies to guard and defend high-priority and overseas Navy bases. Security for the Presidential Retreat located aboard the Naval Support Activity Thurmont, aka Camp David is provided by the Marine infantry battalion stationed as part of the garrison aboard Marine Barracks Washington.

Cooperation between the two services includes the training and instruction of some future Marine Corps officers (most are trained and commissioned through Marine Corps OCS), all Marine Corps Naval Aviators (aircraft pilots) and Naval Flight Officers (airborne weapons and sensor system officers), and some Navy and Marine Corps enlisted personnel. The Corps receives a significant portion of its officers from the United States Naval Academy (USNA) and Naval Reserve Officers Training Corps (NROTC). USNA and NROTC staff and faculty includes Marine Corps instructors. Marine Corps aviators and flight officers are trained in the Naval Air Training Command (NATRACOM) and are designated, or winged as Naval Aviators or Naval Flight Officers. The Marine Corps provides flight instructors to the Naval Air Training Command as well as drill instructors to the Navy's Officer Candidate School. Many enlisted marines, particularly those in the aviation maintenance specialties, are trained at Navy technical training centers. The Marine Corps also provides ground combat training support to various Navy field medical (Hospital Corpsmen), Naval Construction Force (Seabee), and Navy Expeditionary Warfare personnel, units, and commands.

Training alongside each other is viewed as critical, as the Navy provides transport, logistical, and combat support to put Marine units into the fight, such as maritime prepositioning ships and naval gunfire support. Most Marine aviation assets ultimately derive from the Navy, with regard to acquisition, funding, and testing, and Navy aircraft carriers typically deploy with a Marine squadron alongside Navy squadrons. Marines do not recruit or train noncombatants such as chaplains or medical/dental personnel; naval personnel fill these roles. Some of these sailors, particularly Hospital corpsmen and Religious program specialists, generally wear Marine uniforms emblazoned with Navy insignia. Conversely, the Marine Corps is responsible for conducting land operations to support naval campaigns, including the seizure of naval bases. Both services operate a network security team in conjunction.

Marines and sailors share many naval traditions, especially terminology and customs. Marine Corps Medal of Honor recipients wear the Navy variant of this and other awards;^[22] and with few exceptions, the awards and badges of the Navy and Marine Corps are identical. Much of testing for new Marine Corps aircraft is done at Naval Air Station Patuxent River. The Navy's Blue Angels flight demonstration team is staffed by both Navy and Marine officers and enlisted personnel.^[22]

In 2007, the Marine Corps joined with the Navy and Coast Guard to adopt a new maritime strategy called A Cooperative Strategy for 21st Century Seapower that raises the notion of prevention of war to the same philosophical level as the conduct of war.^[174] This new strategy charts a course for the Navy, Coast Guard and Marine Corps to work collectively with each other and international partners to prevent regional crises, man-made or natural, from occurring or reacting quickly should one occur to avoid negative impacts to the United States.

United States Army

The Marine Corps capabilities overlap with those of the United States Army, historically creating competition for funding and missions. The competition dates back to the founding of the Continental Marines, when General George Washington refused to allow the initial Marine battalions to be drawn from among his Continental Army. In the aftermath of World War II, Army leadership made efforts to restructure the American defense establishment including the dissolution of the Marine Corps and the folding of its capabilities into the other services. Leading this movement were such prominent Army officers as General Dwight D. Eisenhower and Army Chief of Staff George C. Marshall.^[67] The Goldwater-Nichols Act significantly reshaped the services roles and relationships with each other, enforcing more joint decision making.^[175] Department of Defense Directive 5100.01 tasks both the Army and Marine Corps with expeditionary and amphibious operations.^[176] With most of the 2000s spent in operations in Afghanistan and Iraq, Secretary of Defense Robert Gates voiced concerns that the Marine Corps are becoming a "second Army".^[29] Since these comments, the Marine Corps has shed its main battle tanks, reduced its size, and focused more on operations in littoral areas where the Army is not explicitly tasked to operate.^[177]

The Army maintains much larger and diverse combat arms, special operations, and logistics forces. The Army has much lighter and expeditionary forces in its infantry and airborne infantry brigade combat teams. The Army also maintains heavier and more logistically taxing armored brigade combat teams.^[178] The Marine Corps, in comparison, maintains forces between these two extremes of mobility and protection. The Marine Corps organizes much smaller deployable units with integrated aviation support. The Marine Corps was historically hesitant to provide forces to U.S. Special Operations Command, instead making specialty units available to its division commanders. The Army has maintained Special Forces, Rangers, civil affairs, psychological operations, special operations aviation, and special missions units for decades. In 2003, the Marine Corps^[179] created the present-day successors to the Marine Raiders and provided them to Special Operations Command starting with the establishment of MCSOCOM Detachment One. The modern Marine Raider training pipeline was based on input from U.S. Army Ranger and Special Forces units.^[103]

Culturally, marines and soldiers share most of the common U.S. military slang and terminology, but the Corps utilizes a large number of naval terms and traditions incompatible with Army lifestyle, as well as their own unique vernacular. As the Army Reserve and Army National Guard is much larger than the Marine Corps's Reserve, many more former active duty marines continue their service in the Army's reserve components.^[180] The Army does not require transfers from the Marines, Air Force Security Forces, or special operations of any branch to attend Army Basic Combat Training.^[181] Due to the requirement that all inter-service transfers attend Marine Corps Recruit Training, very few former soldiers serve in the Marine Corps.

United States Air Force

While some of Marine Corps Aviation assets ultimately derive from the Navy, a large amount of support is drawn from the United States Air Force. The Marine Corps makes extensive use of the USAF Air Mobility Command to airlift marines and equipment, along with utilizing close air support from the Air Force. The Air Force may also attach Tactical Air Control Party units to conventional Marine ground forces to provide coordination for close air support.^[182]

The Air Force traditionally provides the Joint Force Air Component Commander (JFACC) who controls "sorties for air defense, and long range interdiction and reconnaissance" while the MAGTF commander retains control of the Marines' organic aviation assets, however Marine Aviation missions not directly in the support of the MAGTF will be typically controlled by the JFACC.^{[183][184][185]}

United States Coast Guard

The Marine Corps shares a sphere of operation with units of the United States Coast Guard, including operation of the Joint Maritime Training Center (JMTC) (previously known as the Special Missions Training Center (SMTC)), a joint Coast Guard, Navy, and Marine Corps training facility located on the Marine Corps Base Camp Lejeune in Camp Lejeune, North Carolina.
