If so, here's what I would like;
Rifles: M1 Garand/ M1 or M2 Carbine.
SMGs: I'd really like to see a Grease Gun or PPS-43; Thompson would be acceptable, especially a 1928.
MGs: An M1917 or BAR would be a wonderful add-on.
Shotguns- Trench gun, of course.
Snipers- Scoped Springfield would do nicely.
Pistols- If no Makarov or Tokarev, those would be fine.
