United States Forces – Iraq (USF-I) was an American military sub-unified command, part of U.S. Central Command. It was stationed in Iraq as agreed with the Government of Iraq under the U.S.–Iraq Status of Forces Agreement. USF–I replaced the previous commands Multi-National Force – Iraq, Multi-National Corps – Iraq, and Multi-National Security Transition Command – Iraq from January 2010. General Raymond T. Odierno initially served as commanding general but he was replaced by General Lloyd Austin in September of 2010. The logo of the USF-I depicts a lamassu. Background United States Forces – Iraq was the military component of the American and Iraqi bilateral relationship, responsible for defense and security cooperation. The U.S.–Iraq Strategic Framework Agreement reads: In order to strengthen security and stability in Iraq, and thereby contribute to international peace and stability, and to enhance the ability of the Republic of Iraq to deter all threats against its sovereignty, security, and territorial integrity, the Parties shall continue to foster close cooperation concerning defense and security arrangements without prejudice to Iraqi sovereignty over its land, sea, and air territory.

History During 2008 and 2009, all non-U.S. foreign forces withdrew from Iraq. Withdrawal of all non-U.S. forces was complete by 31 July 2009. As of 1 January 2009, the Iraqi government became fully responsible, through its security ministries, for maintaining and providing security and rule of law for its populace. Furthermore, as of 28 June 2009, no foreign forces were stationed within any of Iraq's major cities. The United States decided after negotiations to cease combat operations, that is, patrolling, serving arrest warrants, route clearance, etc., within Iraq by 1 September 2010, and transition to a pure advise, train and assist role. The changing mission entailed major troop reductions; from 115,000 on 15 December 2009, to 50,000 by 1 September 2010, and to zero by 31 December 2011. As a result of the evolution
