(Fort Benning, Ga) – In Week 3 of U.S. Army Sniper School, 35 students participate in the ghillie wash, which is designed to test the strength and durability of the suits as well as weather them. Sniper School students use sand, water and mud, all in an effort to perfect one of their most important tools: their camouflage. (U.S. Army photo by Patrick A.
