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. Stumpff was stranded on a narrow cliff while escaping an enemy ambush, requiring Valkyrie medevac, a dual-state National Guard unit to perform a dangerous hoist extraction under enemy fire while navigating dangerous terrain. Stumpff had been shot in the head by an enemy insurgent, but suffered only a superficial wound as the bullet passed through the back of his helmet, grazed the top of his head, and exited through the front.
