The KV-2, fully named the Kliment Voroshilov 2, is a Heavy Tank based on the KV Series of Russian tanks made from 1939-1945.
Armed with a 152mm M-10T Howitzer, the KV-2 was created after the armaments of the KV-1 were proven to be insufficient to deal with Finnish defenses during the Winter War. Eventually, it was serviced during WW2 and held success with it's armor and firepower until stronger German anti-tank guns were able to penetrate it, relegating it to future obsolescence.
A call for firepower, it's not practical in any way shape or form. However, it's strengths are simple. A big gun on a big chassis. No more, no less.

{ Do not read the Wikipedia of the KV. It's a jumbled fucking mess. }
[ I was honestly not trying my best, but.. It didn't work. It's probably a skill issue but.. I didn't like it. Gun wasn't bad, chassis wasn't bad, it was generally just the enemies and teammates that were the thing that really decided for me. SAP rounds are the best thing to use. ]
