U.S. Marine Corps Cpl. Connor J. Adlington climbs over a wall after emerging from a river during the Jungle Endurance Course at Camp Gonsalves, June 14, 2014. Adlington is a machine gunner with Company K, Battalion Landing Team 3rd Battalion, 5th Marines, 31st Marine Expeditionary Unit, and a native of Menomonee Falls, Wisconsin. Multiple obstacles make up the endurance course, which tests physical and mental stamina, as well as unit cohesion. The 31st MEU is the force of choice for the Asia-Pacific region and is the only continuously forward-deployed MEU. (U.S. Marine Corps photo by Cpl. Henry Antenor)
