you know what we could do instead of sci-fi style tanks is go with a 1946- ? series of tanks...still ww2 technology but more advanced/modified..I've had my mind on a KV-2 for sometime but maybe an upgunned version with two guns in the turret, muzzle breaks(like on an SU-152),and some additional side armor platingor something like that...that would still be somewhat plausible..even if it is just for fun.....call it a "KV-100"
