Soldiers of Company C, 2nd Special Troops Battalion, 2nd Armored Brigade Combat Team, 4th Infantry Division, set off a controlled detonation at Udairi Range Complex near Camp Buehring, Kuwait, Dec. 30, 2103. Before the blast went off, soldiers “buttoned up” inside their vehicles, which meant no one was outside during the detonation. (U.S. Army photo by Staff Sgt. Andrew Porch, 2nd ABCT PAO, 4th Inf. Div.)
