Marine recruit Adam Pendleton, Platoon 1066, Alpha Company, 1st Recruit Training Battalion, holds up barbed wire so his fellow recruits can crawl under on Aug. 26 at Parris Island, S.C. Barbed wire is one of the many obstacles on the combat training course, a part of basic warrior training, held during the ninth week of boot camp, which focuses on basic field-related skills all Marines must know. The basic combat training recruits receive while on Parris Island will be broadened after boot camp during follow-on training at Camp Lejeune, N.C. Pendleton, 18, is from Wellington. Parris Island has been the site of Marine Corps recruit training since 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.
