Cpl. Michael McGinnis, a land navigation instructor, shows recruits of Lima Company, 3rd Recruit Training Battalion, how to use their map and compass Nov. 21, 2013, on Parris Island, S.C. Recruits were sent in teams into a wooded area on the island to ensure they were confident in their abilities to navigate foreign terrain using these simple tools should electronic navigation ever fail them. McGinnis, 24, is from Modesto, Calif. Lima Company is scheduled to graduate Dec. 13, 2013. 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)
