Paul De Gelder, an Australian Wounded Warrior with the Allies Team, dives in the pool at the start of the 100-meter race, during the 2012 Marine Corps Trials, hosted by the Wounded Warrior Regiment, at Marine Corps Base Camp Pendleton, Calif., Feb. 21, 2012. De Gelder lost right leg and hand in a shark attack. Wounded Warrior Marines, veterans and allies are competing in the second annual trials, which include swimming, wheelchair basketball, sitting volleyball, track and field, archery and shooting. The top 50 performing Marines will earn the opportunity to compete in the Warrior Games in Colorado Springs, Colo., in May.
