Four-year-old Christopher Fangerow, from southern California, plays basketball with Staff Sgt. Nestor Cruz after the east vs. allies game of the 2012 Marine Corps Trials at Marine Corps Base Camp Pendleton, Calif., Feb. 18. More than 300 injured Marines from the Wounded Warrior Regiment, in addition to veterans and allies, are competing in the second annual Trials, which include swimming, wheelchair basketball, sitting volleyball, track and field, archery, cycling and shooting. The top 50 performing Marines will earn the opportunity to compete in the Warrior Games in Colorado Springs, Colo., in May.
