U.S. Army Spc. Terry Mills, of Brandon, Miss., pulls U.S. Army Staff Sgt. Ryan Stumpff, Fort Bragg, N.C., into a Black Hawk medevac helicopter July 4 in Khowst province, Afghanistan. The Valkyrie medevac crew was practicing hoist extraction techniques on Forward Operating Base Salerno. Their training was called in to action later that day during an urgent medevac call which required a total of five hoists in tree-and-boulder littered terrain, making the operation both difficult and dangerous.
