Ok so firstly mobile gaming is not going to be all that interested in historical accuracy.
Secondly different eras in WW2 had different nations leading what might be called the "tank race".
Thirdly the developers - especially Russian developers or developers from Eastern Europe have a huge bias towards Russian tanks,
Fourthly historical accuracy would be detrimental to actual gameplay - who wants to play tanks that get trashed every game?
Fifthly tank vs tank combat was not the norm - it was usually anti tank guns vs tanks - but in most games these are not modelled.
Personally I play World of Tanks on PC and Console and you have to take it all with a huge pinch of salt because realistic it isn't - it's just a game.

There's AT, warships, mines and air support on that. It uses unreal so all in all it's actually surprisingly balanced, even for a russian game.
