MARINE CORPS BASE CAMP PENDLETON, Calif. - A Marine attending the Prescout Sniper Course with 1st Marine Division Schools sets up his firing position during a stalking exercise here, Nov. 20, 2013. The teachers required the students to get within 200 yards of their mock objective and acquire personal identification on their targets. The teachers also searched for their students and sent them back to the start point when caught. This emphasized the importance of staying low to the ground and out of sight.
