The MEK Compound (Mujahedin-E Khalq) in Fallujah, Iraq (also known as Camp Fallujah) is a large compound used by the U.S. Marines from 2004 to 2009. Prior to Marine occupation, the Iranian dissident group called Mujahideen-e-Khalq used the MEK as a training camp, but turned it over to the U.S. Army 3d Armored Cavalry Regiment on May 11, 2003 after the Mujahideen-e-Khalq surrender. On March 24, 2004, the 1st Marine Expeditionary Force took over the facility and used it as a base camp. On January 12, 2009, the Government of Iraq took control of the compound from the United States military. As of January 2010, the camp appears to be the headquarters of the Iraqi Army's 1st Division. The last US force to occupy Camp Fallujah was Guardian Company, IMHG, FMF west.
