Marines participate in the 50-mile hike challenge, May 15-17, 2017, at Combined Arms Training Center Camp Fuji, Japan. The 50-mile hike challenge dates back to 1908 when President Theodore Roosevelt signed Executive Order 989, requiring lieutenants and captains in the Marine Corps to walk 50-miles in no more than 20 hours. The Marines are with 3rd Battalion, 8th Marine Regiment forward deployed from Camp Lejeune, North Carolina to III Marine Expeditionary Force under the unit deployment program. (Photo courtesy of Maj.
