Multi-national Corps-Iraq (MNC-I) is the highest-level operational land forces headquarters in Iraq, built around a U.S. corps headquarters that deploys to Iraq, and commands a large number of divisions. It reports to the overall coalition headquarters in Iraq, Multi-National Force-Iraq (MNF-I).
Before the creation of MNF-I, but after the defeat of the regular Iraqi military, the senior U.S. occupation force was first Joint Task Force 7. A corps headquarters was simply too small for the range of responsibilities for occupation, rear area operations, rebuilding a new Iraqi security organization, and counterterrorism; one of the contributing factors to the inappropriate handling of prisoners Abu Ghraib prison may have been a lack of adequate senior staff supervision.
Currently, MNC-I is built around a U.S. corps headquarters, commanded by LTG Charles H. Jacoby Jr., United States Army. His deputies are MG W.H. Moore, British Army and John (JD) Johnson, U.S. Army. The command team includes two additional brigadier generals, Heidi Brown (U.S. Army) for sustainment and Peter C. Bayer, Jr. as Chief of Staff. CSM Frank Grippe is the Command Sergeant Major.
