Captain

The army rank of captain is a commissioned officer rank historically corresponding to the command of a company of soldiers. The rank is also used by some air forces and marine forces, but usually refers to a more senior officer. Today, a captain is typically either the commander or second-in-command of a company or artillery battery. In the Chinese People's Liberation Army, a captain may also command a company, or be the second-in-command of a battalion.

A sea captain, ship's captain, captain, master, or shipmaster, is a high-grade licensed mariner who holds ultimate command and responsibility of a merchant vessel. The captain is responsible for the safe and efficient operation of the ship, including its seaworthiness, safety and security, cargo operations, navigation, crew management, and legal compliance, and for the persons and cargo on board.

The pilot in command (PIC) of an aircraft is the person aboard the aircraft who is ultimately responsible for its operation and safety during flight. This would be the captain in a typical two- or three-pilot aircrew, or "pilot" if there is only one certificated and qualified pilot at the controls of an aircraft. The PIC must be legally certificated to operate the aircraft for the specific flight and flight conditions, but need not be actually manipulating the controls at any given moment. The PIC is the person legally in charge of the aircraft and its flight safety and operation, and would normally be the primary person liable for an infraction of any flight rule.

In the 19th century, a captain of industry was a business leader whose means of amassing a personal fortune contributed positively to the country in some way. This may have been through increased productivity, expansion of markets, providing more jobs, or acts of philanthropy. This characterization contrasts with that of the robber baron, a business leader using political means to achieve personal ends.
