Marines in Corporals Course 4-16 load a casualty on to a litter during a casualty and resupply run at Marine Forces Reserve, Sept. 28, 2016. Throughout the run, Marines took simulated enemy contact and had to react quickly and efficiently to ensure the casualties were transported safely to the end point. The Marines had to work together to problem solve and motivate each other to accomplish the mission. (U.S. Marine Corps photo by Cpl. Melissa Martens)
