Sergeant Major Michael T. Mack addresses the attendees of the opening ceremonies at the 2015 Marine Corps Trials. The Marine Corps Trials provides opportunities for the Marines to train as athletes, while increasing their strength so they can continue their military service or develop healthy habits for life outside the service. The Marine Corps Wounded Warrior Regiment enables wounded, ill, or injured Marines to focus on their abilities and to find new avenues to thrive. The fifth annual Marine Corps Trials is being held at Marine Corps Base Camp Pendleton, Calif., March 3-11. Athletes will compete in archery, cycling, shooting, swimming, track, field, sitting volleyball, and wheelchair basketball. (Photo by Patrick Onofre)
