When viewed at certain distances the Czech Paratrooper Backpack (DPM) switches to the Czech camo pattern. For example in the attached screenshot everyone has the DPM version of the backpack but the guy furthest away (wearing the beret) has changed to the Czech camouflage texture.
To reproduce, place two guys in the editor one with the Czech Paratrooper Backpack (DPM). As the leader, order the backpack guy to move off to a far distance, watch as the texture changes as he gets further away.
Hardly game breaking but figured I'd make a report.
