SU-85 is a Polish Anti-tank unit in Steel Division II.
The SU-85 was a self-propelled gun designed by Lew Trojanow in response to a call for a dedicated anti-tank armored fighting vehicle capable of fighting Panther and Tiger tanks. Combining the SU-122's casemate chassis with the newly developed 85mm D-5 gun, the SU-85 entered production at the Uralmash factory in mid-1943, with first operational units issued to frontline units in August. Production was halted in the spring of 1944, after T-34/85 mass production intensified. "Only" 2 050 units were produced, with production shifting to the much more powerful SU-100.
