The Soviet Prototype Tank is a very massive tank, unlike many other tanks used by the Soviets in the War in Afghanistan, commanded by Lev Kravchenko.
Call of Duty: Black Ops II
The tank appears near the end of the mission "Old Wounds" as part of a final desperate assault by the Soviets on the Mujahideen base in Afghanistan. It is very wide and has two cannon barrels side by side. The Mujahideen leads a suicide charge against it and Alex Mason, with the help of Frank Woods, manages to board the tank, pulling out Kravchenko before destroying it with an explosive mortar.
