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-Qa'im, and Haditha. The force was the most important U.S. unit to take part in the Iraq War in Al Anbar Governorate.
Among the smaller multinational units operating within MNF-W was a platoon from the Azerbaijani Armed Forces.
