42nd Motorized Infantry Battalion (Ukraine)

The Battle of Ilovaisk started on 7 August 2014, when the Armed Forces of Ukraine and pro-Ukrainian paramilitaries began a series of attempts to capture the city of Ilovaisk from pro-Russian insurgents affiliated with the Donetsk People's Republic (DPR) and detachments of the Russian Armed Forces. Although Ukrainian forces were able to enter the city on 18 August, they were encircled between 24 and 26 August by overwhelming Russian-backed military groups. After days of encirclement, Ukrainian forces rejected the DPR's proposal to open a humanitarian corridor on the condition that they abandon their armored vehicles and ammunition, and on the morning of 29 August 2014 began to leave Ilovaisk with their weapons. The Russian side opened fire on the evacuating Ukrainian soldiers, many of whom died whilst trying to escape.

An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit.
