The SU-85 (Samokhodnaya ustanovka 85) was a Soviet self-propelled gun used during World War II, based on the chassis of the T-34 medium tank. Earlier Soviet self-propelled guns were meant to serve as either assault guns, such as the SU-122, or as tank destroyers; the SU-85 fell into the latter category. As with the other AFVs in the SU series, the designation "85" refers to the vehicle's main armament, the 85 mm D-5T gun.
