If we look at the large scale, throughout the war Soviet armor performed poorly. For whatever reason that is (crews, handheld AT and AT guns, tactics, doctrine, the tank design, radios etc.). Soviet super tanks - like you want them - are out of place.
i dont undestand what u talking about?!
what period of war/ whats tanks ?! if u so incompetent there's no difference at all about armor/
(1941) pz-3 destroy t-26/t-28 and another
(1941-1943) t-34-76/KV-1 destroy pz-3/early pz-4/stug the germans upgades guns to 76 mm (pz-4 have about 10 modifications) for successful fight with t34-76.
(1943) germans made NEW panters / tigers / elefants destroy t-34 main tanks for superiority in the battlefield (the panther is created on the basis of technology of inclined armor soviet t34)
(1943)soviet upgades tanks to t34-85 / su - 85 just as Germans earlier replase pz-4 but it isn't enough. Mades new Kv-85 (Kv-1s technology) - small period than Is-1. upgrade su-85 to su-100. Mades new isu-122/isu-152/Is-2 for offensive operations.
(1945)And new is-3 on military parade in Berlin in 1945 but this tanks didn't participate in fights, but were already made.
large calibers ignore armor, the distance, tactics, experience and other reasons is important
