The T-35 was a huge Soviet tank with multiple cannon and gun turrets!
It wasn't very succesful on the battlefield, because it suffered from many technical and mechanical failures, but I like to think it might have been the inspiration for the huge, super-deformed Megatanks from the Advance Wars series! (you can get the papercraft models of those in the Advance Wars section of my own papercraft webpage: link ;o)
(Black Hole likes having lots of cannons on one tank too! ;o)
