The Multi-National Force - Iraq (MNF-I) is a military command, led by the United States, that is fighting the Iraq War against Iraqi insurgents or resistants. Multi-National Force - Iraq replaced the previous force, Combined Joint Task Force 7, on May 15, 2004. General Ray Odierno serves as Commanding General. The media in the U.S. generally used the term "U.S.-led coalition" to describe this force, as the vast majority of the troops were from the United States. The majority of nations that deployed troops confined them to their bases due to widespread violence. Additionally, the deployment of troops and the war itself was highly unpopular in many of the countries that participated in the Multinational Force. Also in Iraq, but not part of MNF-I, are the United Nations Assistance Mission in Iraq, which is doing humanitarian work, but has a number of guards and military observers, and the NATO Training Mission - Iraq, training the Iraqi army and police force. The Force was significantly reinforced during the Iraq War troop surge of 2007.
