Sapper Stakes 2015
A crater charge explodes on a demolition range event as part of Sapper Stakes 2015 competition at Fort Chaffe, Ark., Sept. 1. Combat engineers use demolition in mobility and counter-mobility to both allow movement to allies and impede movement for enemy forces. The competition is designed to build teamwork, enhance combat engineering skills and promote leadership among the units. (U.S. Army photo by Master Sgt. Michel Sauret).
