Brittany Longshore cheers for her new Marine brother, Pvt. Cory Crow, Platoon 3014, Kilo Company, 3rd Recruit Training Battalion, during a motivation run on Parris Island, S.C., Jan. 28, 2016. The motivation run is the first time family and friends get to see their new Marines in almost 13 weeks. Kilo Company is scheduled to graduate Jan. 29, 2016. Parris Island has been the site of Marine Corps recruit training since Nov. 1, 1915. Today, approximately 19,000 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 approximately 50 percent of male recruits and 100 percent of female recruits in the Marine Corps. (Photo by Staff Sgt. Greg Thomas)
