U.S. Marine Staff Sgt. Marcus A. Rains, a Combat Instructor with the School of Infantry-East, draws his M9 Pistol during the two-gun live fire portion of the Combat Instructor Stakes on Camp Lejeune, N.C., March 16, 2015. The School of Infantry-East hosted the Combat Instructor Stakes, which is a grueling 30-hour competition that pits two man teams against each other, competing in physical, tactical and knowledge based events while carrying a combat load and moving over 50 kilometers on foot.
