The PACV was armed with twin .50 caliber M2 Browning machine guns in a roof-mounted turret in the front and two 7.62mm M60 machine guns, one port and one starboard. The Army initially equipped their hovercraft with a minigun and 40 mm M5 automatic grenade launcher as well. Only one ACV was outfitted with a grenade launcher, however, and the miniguns were removed to make space for more troops and cargo because it was found to be effective only for suppressive fire.
