well, comparing the KV-2 to these tanks is not quite fair that's why i think it is ridicullous to put it even in the game lol.... hiostorically seen, in 1942 the KV-2 was already out of service when the Germans introduced Panzer IV and Hetzer.
That's why the KV-2 has no chance against almost all german tanks that came after 1942.
its armor was not able to resist german anti tank guns
and the 152mm was more a large calibred mortar than a howitzer.
It could barely break the side armor of a Panzer 4 not more...
Yep but not only that, the whole urban combat doctrine is silly underpowered compared to the other two super doctrines.
