Muharraq Airfield is a military base located adjacent to Bahrain International Airport. It is run by the United States Navy (USN) and usually ships supplies in and out of the airport with many of them from other countries as well. The USN, the United States Marine Corps (USMC), the Ministry of Interior, and others run the security at the airfield. Often referred to as the nearby city of Manama, Muharraq Airfield was the last stop for most US troops headed to join the NATO forces in Afghanistan.
