In WW2 you got issued one personal weapon. That would only change if you A) captured an enemy weapon and decided to accept the risks and supply issues, and still carry/safely store your issued weapon (can't throw away government property) or your position changed through promotion. So if you started as a private in the infantry, and never went beyond that for whatever reason, you only carried that rifle you were issued. Pistols depended generally on what you were doing, in US army it would be for officers and some NCOs, for German army anyone who served a crew weapon was issued a pistol. That said, again, your average soldier did not have a pistol unless he purchased one privately and kept it as a pocket pistol (so it wouldn't be a Luger or such, think more PPK, Cz27, Sauer 38, etc etc). Again, we will represent pistols/weapon issue accurately ingame, and not at all like games such as Call of Duty.
@battleaxe: Yes I do agree doing rarer things would be fun. As for Belgian stuff, it would be rather easy to figure out WHAT to make, just would have to look and see what the Eben Emael garrison was issued. Problems of course would be having to essentially scratch build two entire armies (remember, german player models of 1944 look nothing like FJ of 1940), and also scratch build all the bunker stuff, and all for a single map. If we did Eben Emael, it would only be if we went off to do the entire 1940 campaign.
