ghillie suit

A real life garment used by the military, a poncho like material is attached with fresh leafs and woodland materials so the user can blend in with the given enviroment. A suit donned by Snipers, typically SAS and such. The Ghillie has also featured in FPS video games, COD4, CODWAW, this gives the user(a sniper can only use them) a tactical advantage when it comes to grassy areas, but the developers pulled them off poorly and they rarely work.
