An M1A1 Abrams battle tank from Tank Platoon, Battalion Landing Team 1st Battalion, 9th Marine Regiment, 24th Marine Expeditionary Unit, fires on the move while assault amphibian vehicles (AAV) support infantrymen during a mechanized assault on a live-fire training range in Djibouti, Africa, March 29, 2010. The AAV platoon and tank platoon worked hand-in-hand with infantrymen from Alpha Company, BLT 1/9, 24th MEU, in the mountainous, desert environment to provide an intense, realistic training experience of infantry Marines being supported by armored assets while in the attack. 24th MEU Marines performed a series of sustainment exercises, as well as bi-lateral training alongside the French military, during a month-long rotation of units from 24th MEU conducting training in the east-African country. The 24th MEU currently serves as the theatre reserve force for Central Command. (U.S. Marine Corps photo by Gunnery Sgt. Chad R. Kiehl)
