In military tents and more specifically in small guardhouse buildings (ones with three rooms, locker room areas with a seperate toilet room and another door that leads to a room with a computer and a few desks) usually spawns police loot ie. mp5 ,scorpion, 45cal pistols & silencers etc. Loot spawns on the top shelf of lockers usually mags for smgs and pistol suppressor but there always clipping into the shelf and cannot be picked up, tried in vicinity. Tried jumping on a friends back to get a different angle etc but no luck. Same with many military tents where magazines , and ammo stacks/boxes clip into bunk beds and boxes constantly. Can usually be worked around with a lot of changing height/angle from loot object. Hope this helps
