OffTopic: Would you stop with the historical discussions? As long as they fill the spirit of things no need for details.
This game is based on history. Even more, in some things Relic tries actually to follow it, like bringing fuel and munition starved OKW faction in general
(yeah, plenty of stuff is broken beyond normal, but WWII is highly controversial)
Still, if you design something based on history, you should take history into account.
As for game purpose. Isn't it strange to combine DP with short-ranged SVT?
