The M811A2 Monitor AVP was a tank built on a new chassis to feature a 90mm Anti Tank gun. The vehicle its self is longer and wider than the scorpion chassing though marginly lower than it. The main chassis is a boxy chassis in a trapezoid shape, with a front sloped plate, sporting the turret mounted 90mm Gauss gun and mounting a 20mm remote operated turret, providing anti infantry defence and a remote operated .50 cal defence MG on the rear to aid in defence and escape.
