Multi-National Force West

Multi-National Forces West (MNF-W) or United States Forces West (USF-W) was one of the coalition headquarters under Multi-National Force-Iraq. It was headquartered by either I or II U.S. Marine Expeditionary Force that rotated on a 12-month basis. Their area of operations was primarily the Al Anbar province which includes the cities of Ar Ramadi, Fallujah, Al Qaim, and Haditha. The force was the most important U.S. unit to take part in the Iraq War in Anbar Province.

Among the smaller multinational units operating within MNF-W was a platoon from the Azerbaijani Armed Forces.

Commanders
During the Iraq War, the Marine Corps regularly rotated command of MNF-W between the 1st and 2nd Marine Expeditionary Forces.

For convenience, these changes of command are listed below and the Marine command in MNF-W is simply referred to as "MEF":

As the Marine Corps withdrew from Anbar Province, by September 2009 they were replaced by a single brigade, the 1st Brigade of the 82nd Airborne Division. The brigade was bolstered with an additional 16 advisers, though this did not reach the 48 assigned advisors that were supposed to be part of an 'Advise and Assist' brigade.
