U.S. Marine Corps Drill Instructor Staff Sgt. Jonathan Peterson orders a recruit of Mike Company, 3rd Recruit Training Battalion, to run backwards after rappelling down a wall May 1, 2018, on Parris Island, S.C. Drill instructors, like Peterson, 26, from Fridley, Minn., belay on the ground as recruits rappel from the 47-foot-tall tower to stop them from falling if they lose control. Mike Company is scheduled to graduate July 6, 2018. (Photo by Lance Cpl. Carlin Warren)
