Varying media estimates of military forces in Iraq have raised concerns about the actual number of troops deployed in Operation Iraqi Freedom (OIF). Last year, a major announcement on a surge in troop deployments to Iraq by President Bush included a planned gradual increase of more than 20,000 U.S. troops on the ground in Baghdad and Anbar province over several months. Since the "new strategy for Iraq" speech by the President in January 2007, troop deployments gradually increased during the months of February through October 2007 but decreased beginning in November 2007. This report provides solely Department of Defense (DOD) statistical information on U.S. forces serving in Iraq. It also provides brief official information on the military units schedule for the next rotation of duty into Iraq.
