Which I always thought was a funny design decision. That's why you get squad wipes on the Ost side as Soviets because they have a max of 4 models per squad. You'd think AI would be a German priority when Russians are throwing bodies with their 6 model squad armies. ISU-152 is nicknamed the "beast killer," and imagine if it lived up to it's name ingame. Instead you have this:
Elefant is 76% better at killing tanks compared to ISU-152 (elefant also has double armor and 33% more health)
Elefant deals 36.4 DPS at 170 Pen
ISU-152 deals 23.4 DPS at 150 Pen
Elefant kills ISU-152 is 30 sec
ISU-152 kills elefant in 140 Sec
Elefant has double armor and 33% more health
Elefant costs 9% less than the ISU-152

Great AI unit, but I always felt the KV2 was a better AT unit than the ISU (unless you're a microing god...killing a KV2 in a duo with a sliver of health Panther felt like a great achievement). When you see Soviet's (which I am as well) play aggressively, this is one of the reasons. They don't want to drag the game any longer than they should; or face heavy AT units late game.
