DJIBOUTI (Oct. 7, 2012) - A Marine with Bravo Company, Battalion Landing Team 1st Battalion, 2nd Marine Regiment, 24th Marine Expeditionary Unit, performs pull-ups while competing in the 'Training Force Challenge' in Djibouti, Oct. 7, 2012. The challenge was part of a three-week training force package, which paired Marines of Bravo Company with Marines of Combat Logistics Battalion 24, to gain a shared understanding of each other's roles in the Marine Corps Air Ground Task Force and refine their basic infantry skills in Djibouti's rugged terrain. The package comprised basic infantry skills, desert survival techniques, endurance courses and a simulated war. The 24th MEU is deployed with the Iwo Jima Amphibious Ready Group as a theater reserve and crisis response force in the U.S. Central Command and U.S. Navy's 5th Fleet area of responsibility.
