Marines and Sailors with the 31st Marine Expeditionary

Marines and Sailors with the 31st Marine Expeditionary Unit march in formation during a conditioning hike at Camp Hansen, Okinawa, Japan, Feb. 15, 2019. Marines and Sailors with the 31st MEU’s Command Element, the aptly named command and control element for the Marine Corps’ only continuously forward-deployed MEU, completed a more than five-kilometer hike to build conditioning and prepare its Marines and Sailors for the rigors of amphibious operations. The 31st MEU, partnering with the Wasp Amphibious Ready Group, provides a flexible and lethal force ready to perform a wide range of military operations as the premier crisis response force in the Indo-Pacific region.
