In 1943 the Soviets began developing the SU-85 in response to German armour seen in 1942 such as the Tiger tank as well as armour understood to be in development at the time. Although several options were explored, the SU-85 was one of the results. The SU-85 was a typical Self-propelled Anti-Tank Gun; with a D-5T 85 mm antitank gun mounted in the superstructure with limited traverse. During the Second World War the Germans would capture weapons from numerous nations including the Russians; the SU-85 was no exception and like other captured stock the Germans pressed it into service with the designation Jagdpanzer SU-85(r) (JagdPz-85(r)). The below pictures reflect captured SU-85s in German service.
