Brian Onofrio’s technique during an introduction to the Marine Corps Martial Arts Program June 3, 2014, on Parris Island, S.C. Driven by the philosophy of "one mind, any weapon," MCMAP combines some of the most effective unarmed techniques from various martial arts with armed techniques designed for combat. Owens, 28, is from Ocala, Fla. Onofrio, 22, from Madison, Conn., is scheduled to graduate Aug. 22, 2014. Parris Island has been the site of Marine Corps recruit training since Nov. 1, 1915. Today, approximately 20,000 recruits come to Parris Island annually for the chance to become United States Marines by enduring 13 weeks of rigorous, transformative training. Parris Island is home to entry-level enlisted training for 50 percent of males and 100 percent of females in the Marine Corps. (Photo by Cpl. Caitlin Brink)
