I have seen pictures of Su-152’s just as wrecked as these pictures of what an Su-152 victims...
Average tank in my opinion. Its gun caliber alone making it a brutal tank killer but a tank that could easily get wrecked itself.
That would be because the SU-152 wasn’t a tank and it wasn’t originally designed as a tank destroyer either. It was supposed to be a mobile assault gun. The Soviets noted that their assault guns tended to do a very good job of blowing up German tanks due to their huge HE shells and pressed them into service as TDs. Then they started deliberately making them into TDs, with the ISU-152, etc.
