Quoting nathan Yauck
Great job! you just got a fave builder from me dude! though certain brickarms weapons are not WWII, like that assault rifle with scope.
All of the weapons I use for my WW2 soldiers were used during WW2. The assault rifle my Germans are using is an StG-44/MP-44, one of the worlds first AR's, it was developed in Germany during WW2 and and it was a major design influence for the well known AK-47.
