I think that where the bunker slots are where the mg 42s are placed to make that area a shadow so no snipers could see them, but see there fire from the guns therefor they would have to guess where to shoot. Or they could make the map hella foggy so no sniping is posable at all until u get close to the bunkers but its too late then when you getting fired at......
