What I know, the swastika was only when they attack positions combined with aviation (principaly at the beginin of the war, but rarely in 1943) and was flags put by the crew on the rear top of the tanks (like bellow):
But if someone knows more, don't hesitate to give us some informations (or a link... I like learn about WW2... in english pls my german is worse than english).
It's a little boring for german gamers... Without gore, swastika... Your administration think you will go in war if you see too much blood or flags ?!?
Europe is not what it was before... and people (mentality) is different too (IMO)
