U.S. Army Spc. Paul Islas, assigned to D Company, 2-159th Attack Reconnaissance Battalion, 12th Combat Aviation Brigade, navigates through a land navigation course, part of the European Best Warrior Competition in Grafenwoehr, Germany, Sept. 14, 2014. The competition is a weeklong event that pushes Soldiers to the limits of their physical stamina, bearing, knowledge, adaptability and technical and tactical skills. The best warriors are ready and resilient Soldiers who live the Army values and lead from the front. (U.S. Army photo by Staff Sgt. Pablo N. Piedra/Released)
