I havent done this ISU 152 vs Jagdtiger as yet but ISU 152 requires some skill to be handled effectively Its like a "LARGE" field gun , capable of destroying most tanks in 2 hits , but it can be circle strafed easily hence it requires a great deal of support , however you can use it to smash your way through to the enemy base , it is effectively a breakthrough assault tank
ISU-152' skill "animal killer", try to work as a marder lock down, but with the same reload time and accuracy, correct me if I'm wrong .
Jadgpanther reloads alot faster then ISU 152.
ISU-152 can not shoot while moving.
So forget retreating while shooting.
