U.S. Navy medical technicians load a simulated casualty into a medical service HMMWV to bring him to an evacuation site during a Marine Corps Combat Readiness Evaluation completed by 1st Medical Battalion, 1st Marine Logistics Group at Camp Pendleton, Calif., Oct 17-21, 2016. The MCCRE was designed to push the Sailors and Marines to the limit with scenarios they would be likely to see in a combat environment such as improvised explosive devices, downed aircraft and mass casualty drills. Marines and Sailors were required to work side-by-side to ensure mission success. (U.S. Marine Corps photo by Lance Cpl. Jocelyn Ontiveros)
