Sitting volleyball coach, Greg Walker from Huntington, Penn., addresses the athletes during a break in training during the 2014 Marine Corps Trials aboard Camp Pendleton, Calif., March 4, 2014. The Marine Corps Trials is an 8-sport invitational involving four competing teams comprised of active duty Marines, veterans and international service members. Athletes will have the opportunity to compete in an eight-sport competition to include archery, shooting, wheelchair basketball, sitting volleyball, swimming, cycling, track, and field events. The competition 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.
