Multi-National Force - Iraq (MNF-I) was the highest military headquarters for foreign troops in Iraq. It reports to United States Central Command. Under the new security agreement with Iraq, it has been redesignated United States Forces - Iraq, and no longer has a senior British deputy.
At present, it is commanded by a U.S. general, GEN Ray Odierno, with a British lieutenant general deputy, LTG Chris Brown. Prior to the Abu Ghraib prison disclosures and prosecution, the senior headquarters had been Multi-National Corps-Iraq (MNC-I), and one of the resulting reforms was to create a higher headquarters in Iraq, allowing the MNC-I commander to concentrate on military operations. Its first commander was GEN George Casey, now Chief of Staff of the Army.
MNC-I remains the main headquarters for combat units, but other support and Iraqi reconstruction functions, report to MNF-I.
