The primary command and control vehicle for commanders and staff in tank destroyer battalions was the M20 Armored Utility Car. Essentially an M8 with its turret removed and a ring mount for an anti-aircraft MG mounted on the roof of the vehicle, its only defense against enemy armor was a bazooka stowed inside. Nevertheless, it provided excellent mobility and protection against small arms fire and shrapnel for its passengers. It also contained additional radio sets to facilitate the exercise of command and control.
