I dont understand?
Why would someone willingly swap their own weapon for that of the enemys?
Disadvantages:
1.)Enemy weapon = enemy weapon sounds, thus confuses your own men
2.)When you run out of ammo, chances are your own nations ammo will be of a different calibre
3.)Against army practise = telling off by senior officer when you return to barracks with an enemy weapon
4.)Sights not aligned to your own eyes = poor accuracy
5.)Untrained with enemys weaponary.
Advantages:
1.)Enemy weapon may be superior to your own weapon
2.)You may have 'lost' or had your own weapon damaged, so one weapon is better than no weapon.
3.)You may have run out of ammo with your own weapon so you pick up an enemys weapon with ammo already loaded.
Other extras:
--- An ordinary rifle man using a Kar98 might find it a bonus to see an enemys sniper rifle and for the first time be able to use a scope which he was not/ and possible cannot get hold of.
--- No rifle man, in my opinion would be allowed nor would bother to switch his rifle, which he has trained with for the past 5 years for an enemys MG / rifle which he has absolutely no experience with what so ever.
--- Maybe your army has issued you an enemys weapon which has been looted on the battlefield and converted to the nations standard calibre due to own nations weapon shortages?
In my opinion, Stalingrad was a big cluster-fcuk anyways, it wouldnt surprise me if in the heat of battle a commisioned officer handled at some point a Pzb39 and took out 4 T-34s in the space of 30 minutes or a Soviet rifleman looted an Mg34 and wiped out a whole comany of Germans on his own.
