Vlim, for sure this fatty guy is far to be an example of elite infantry soldier.
I just add my point to clarify that a
stockless LP08 has his tactical justification in the West front perspective where the Sturmtruppen, during close combat in the trenches, were more interested in the volume of fire than in the precision. This is why is quite common to see pictures of infantry soldiers wearing a LP08 w/o stock and also why it is common to find holsters modified to be carryed in the belt.
But you are right nothing to do with the fatty soldier in the photo.
Cheers,
Mauro
