I am enjoying my experience with enlisted so far. One thing that I think would increase immersion is historical equipment for your soldiers. Real soldiers in WW2 were not riding into combat with only suspenders and a belt. As far as I know, all militaries had a set of individual gear for carrying ammo, food, personal equipment, etc.
Historical ammo loads- I know that the amount of ammo carried by the soldier in enlisted has to do with balance, but I feel that having historical ammo loads would make more sense, and with most individual gear systems being modular one could still pick and choose how much ammo was carried.
I am going to use the American infantry in Normandy as my prime example for this. This is my area of the most expertise.
In the Normandy campaign, most soldiers appear to be carrying just a pistol belt, or a pistol belt and suspenders. Most infantrymen were riflemen, and therefore carried an assembly based around the M-1928 Cartridge belt. This would commonly be worn with suspenders, either an M-1928 haversack or (possibly) a M-1936 Musette bag (commonly used by paratroopers) or the M-1944 combat/cargo pack assembly. Also commonly worn on the belt was a Medkit pouch, a canteen, and perhaps a bayonet. An entrenching tool was also commonly worn on the pack.
The M-1928 cartridge belt could accommodate 80 rounds for the garand or 100 rounds for the Springfield. Pistol belts with different ammo pouches were worn for guns like the M1 carbine, M3 sub machine gun, etc.
Bandoliers were also used to carry additional ammo for the Springfield, M1 Garand, and M1 Carbine.
An M1 general purpose ammunition bag also existed for the purpose of carrying ammo. This thing could hold about anything you wanted it to (bazooka rockets, grenades…)
M1 Garand- 80 rounds carried. Addition of small and large ammo pouches could be added in as a half-full or completely full bandolier.
M1903 Springfield- 100 rounds carried. Addition of extra ammo pouches could be worked in as a bandolier.
M1 Carbine- 60 rounds carried. Addition of “small ammo pouch” could be represented as an additional pouch on the stock. Addition of “large ammo pouch” could be represented by a bandolier.
This is all of the information that I can strongly back. I am not an expert with other guns and their carried ammunition.
