U.S. Marine Corps Lance Cpl. Ronald Sullivan prepares to serve a volleyball in the East vs. Veterans championship volleyball game for the 2012 Marine Corps Trials at Marine Corps Base Camp Pendleton, Calif., Feb. 21, 2012. More than 300 injured U.S. Marines with the Wounded Warrior Regiment, in addition to veterans and allies, competed in the second annual trials, which included swimming, wheelchair basketball, sitting volleyball, track and field, archery, cycling and shooting. The top 50 performing Marines earned the opportunity to compete in the Warrior Games in Colorado Springs, Colo., in May 2012.
