This sniper post is used to house a single sniper. a food supply is located at the base of the sniper post, the sniper can live in the post for months on end. The bubble like structures are unique forcefields, bullets cannot pass through them, but the advanced sniper rifle used by the sniper can disrupt the shield so the rifle could poke out and freely move and fire through the shield. The snipers are placed by flying vehicles in the sniper posts, thus the lack of ladders and such, because of this sniper posts cannot be used by foes, but the food supply can be looted if the sniper is somehow killed.
