The AAV-7A1 AMTRAC, better known as the Amphibious Assault Vehicle, or simply AAV, is a tracked armored personnel carrier used by the United States Marine Corps and it is built by US Combat Systems, a subset of BAE Systems Land & Armaments. "AMTRAC" is a contraction of "amphibious tractor." The AAV has been in service with the Alliance of Nations since its introduction.

The vehicle is capable of being launched from the sea by amphibious dock ships to bring assault elements quickly to the shore as well as provide combat support with a mounted Mk 19 grenade launcher or M242 Bushmaster cannon and the M2 Browning HMG.
