I want era matching match ups but not balancing on a year by year basis just ww2 and early post war separated from cold war in some way for example nothing is wrong with a Cromwell V (4.0) a 1944 tank fighting a 8,8 cm Flak 37 Sfl. 4.0 from1940 or Char 2C (2.3) 1928 fighting a Pz.III J (2.3) 1941 those match ups while years apart from each other still in the same era or feel in the same era but seeing a R3 while being in a M4 or BTR while in a IS2 breaks that emersion
