I would dig in the weapons system:
Stock:
M1 Garand - Kar 98k
Thompson - StG 44
BAR - MG 44
I tought about adding MP 40, Gewehr 43, M3 SMG, M1A1 Carbine.
The MP 40 was more extended than MP 44.
The Gewehr 43 was a response to Garand (semi-auto rifle).
M1A1 Carbine was lighter rifle for Allied paratroopers.
M3 SMG was second most extended SMG after Thompson.
FG 42 was gun for German paratroopers.
M1903 Springfield was also very extended (unscoped ofc)
My:
M1903 Springfield - Kar 98k
Garand/M1A1 - Gewehr 43
Thompson - StG 44
Grease Gun - MP 40
MG 34/42 - BAR
FG 42 - ???
The more weapons makes game more realistic
