Luckily it's just small-scale skirmish battles, so not many (if any) vehicles to worry about.
The weapons, yes absolutely - no MG42's, no Panzerfausts/Panzerschrecks, etc. and of course no MP43/StG44s
Technically there shouldn't even be MP40's (introduced in 1938), but I'm going to kind of let that slide. I mean, if I REALLY wanted to be picky I should be trying to do Reichswehr uniforms, but those look close enough anyway unless you're looking at senior officers and my games are ranging from '34-'39 so the 1936 pattern is a perfectly fine medium for that.
