If you think two SU-85's have more of an impact than a JT then you've gone completely loony.
Also, why do you keep infatuating on rear armor? Newsflash - if the other side is shooting at the rear of either an ISU or a JT, then you messed up.
so 2 su-85 have more impact than a ISU-152 but less than a JT or elefant mhhhh (both will kill medium in 3 hit, only vs very heavy there is some difference but isu has deflection damage)
it's like u are saying isu is UP
If you goal was to prove how little you know about the ISU and how it works, you've succeeded brilliantly. I use both the ISU and JT regularly. The ISU's rate of fire makes it bad against Panthers, Tigers, etc. It isn't a good TD, certainly not as good as getting 2 SU-85's. It needs a larger support army than a JT because it dies easily if someone can dive even a P4 in behind it. I can't remember the last time I lost a JT. I've lost a couple ISU's in the last week when people were able to strip away enough of its support using arty and/or skill planes.
when some tank flank u what's important ?
why is elfeant or jt better vs a flanking tank than a isu if it's slower and have worse rear armor ?
why would diving jt or ele be harder than isu ?
