on array if I have a sniperrifle or longe range weapon, depending on my spawn i will sit lay down directly in front of the snow trail between the open trailer/cargo box and the wall opening. or kneeling up against the radio tower stairs, or in front of the satelite between the tree and car. or up on top of the rocks between the power plants and construction building.
on silo its behind either forklift for a view of sniperpost.
on hangar 18 i like to use the open hangar window at the top to eliminate either a camper in the top of the apple room or the opposite top level hangar room.
otherr than that i do not stay in one spot on any other map, because it makes me paranoid when sitting in one spot. especially with turtle beaches on.
