After the update 1.6, I can not find anything on the military towers.
In Chernarus reduced generation of loot hidden in the texture.

As the respawn loot in the textures occurs not only on military towers, it is also characteristic in other buildings, tents, houses, etc. Loot hidden in textures often do not have an interaction area. A respawn loot is required on the surface of the floor texture. Military towers and hunting towers T138489 allow you to see where the loot is hidden. In other objects T144896 where the loot is hidden, you cannot look at it or see the problem.
