US Forces Order of Battle - 23 August 2004

This is a "best available" listing of US forces deployed to the Central Command AOR for Southwest Asia and for US forces deployed to European Command's locations in Turkey, Romania and Bulgaria. It does not include forces deployed exclusively for operations in Central Asia though it may at times list units that are involved in both Operations Iraqi and Enduring Freedom. This listing also does not account for US or Coalition forces involved in operations in the Horn of Africa.

The task of developing a comprehensive listing of US forces present in the area is particularly difficult as the number of units rotating in and out of Southwest Asia are substantial. The events of Sept. 11, 2001 and the Global War on Terrorism has made such an effort significantly more difficult as the military seeks to improve operational security (OPSEC) and to deceive potential enemies and the media as to the extent of American operations. The significant number of troops that have been mobilized or activated in the United States for unspecified duties, whether they be in support of Iraq Freedom or in support of homeland security also complicates matters as it is not entirely clear what units are going where.

This being the case, mistakes, misidentifications, or ignorance regarding specific units being in the region, or not in the region will occur.

Beginning in late December 2003, the United States began implementing the OIF 2 troop rotation that would begin to bring roughly 130,000 Army personnel out of Iraq and deploy roughly 110,000 troops into Iraq as replacements. The rotation was expected to last until late April 2004 but increasing security concerns in April caused the redeployment of forces to be put on hold for roughly 90 days. Ground forces in the region that were to be replaced included the 101st Airborne Division, 4th Infantry Division, 1st Armored Division, 3rd Armored Cavalry Regiment, 2nd Armored Cavalry Regiment, 173rd Airborne Brigade, and elements of the 82nd Airborne Division. There are also a significant number of echelon above division support units in the region. The Army was rotating in the 1st Cavalry Division, elements of the 1st Infantry Division, elements of the 25th Infantry Division, the 3rd Brigade Combat Team, 2nd Infantry Division and an additional three brigades from the Army National Guard.

The 1st Armored Division, and 2nd Light cavaly Regiment, after having been extended, have begun redeploying home. This process was to be completed for the 2nd LCR by the end of July 2004. Similarly, some of the units of the 1st Armored Division, had, as of July 11, 2004, already redeployed back.

As of early March 2004 over 114,000 US personnel and over 23,000 coalition personnel from 35 nations were deployed in Iraq. Over 26,000 US and Coalition personnel were deployed in Kuwait, providing logistical support to Operation Iraqi Freedom. As of mid-April 2004 the number of troops in the Central Command Area of Responsibility was officially estimated at between 200,00 and 225,000 total. Inside the Horn of Africa there were around 1,200 that dedicate or focus themselves on the Horn of Africa. In Afghanistan there were around 20,000.

An additional 30,000 soldiers are estimated to be operating in Kuwait and other areas of the region supporting operations in Iraq. Thus, the total number of soldiers in Southwest Asia is believed to be about 170,000.

The US Air Force's Expeditionary Air and Space Force (EAF) concept and organization sets a guideline for Air Force deployments to operational locations. The EAF is comprised of 10 Aerospace Expeditionary Forces (AEF) each with lead combat and support wings including on-call wings that could be deployed if required. While deployments for active duty units generally lasts roughly 90-days, Reserve and Guard units deploy typically for 30 - 60 days. Currently, AEF 7 & 8 are deployed, with roughly 17,000 airmen deployed in the CENTCOM AOR according to Stars and Stripes on May 26, 2004.

Naval units include a headquarters and shore-based units comprised of about 1,200 people at Manama in Bahrain. Nearly a thousand civilian mariners are associated with Military Sealift Command ships at Diego Garcia. During the 1990s overall Naval force personnel levels in the CENTCOM AOR typically varied between 8,000 and 15,000. Each Carrier Battle Group, with its associated Carrier Air Wing, has approximately 11,000 sailors embarked. As of 13 July 2004 there was one carrier strike group and one expeditionary strike group in the area for a total of around 17,000 naval personnel. A total of about 501 Vertical Launch System cells are available for Tomahawk cruise missiles, though based on estimates of prior deployments, perhaps as many as 250 Tomahawks are actually deployed. The cruise missile force can be augmented significantly within days.

The Marine presence in Iraq is centered around the I Marine Expeditionary Force and the 1st Marine Division. Two Marine Expeditionary Units, the 11th and 24th MEU have also arrived in the CENTCOM AOR for deployment to Iraq. One Marine Expeditionary Unit is also in the region, though it is currently supporting operations in Afghanistan [and are thus not included in this tally]. On July 7, 2004, Lt. General Jan C. July, Deputy Commandant, Plans, Policies, & Operations, USMC, testified that 26,427 Marines were deployed in Iraq. An additional 657 were deployed in the Horn of Africa. Marine tactical units deploy for seven months. Headquarters and command elements deploy, however, for 12 months periods.

18-plus brigades equivalent were in Iraq, as of July 7, 2004. That number was to dwindle down to 17-plus brigades with the rotation out of the 1st Armored Division and the 2nd Light Cavalry Regiment.

Army/Reserve Component Distribution

Army National Guard/Reserve Troop Numbers

According to July 7 testimony by Lt. General Jan C. July, the Marine Corps troop component distribution was at about 20% Reserves and 80% active duty.

OIF-3 Rotation

Beginning in July 2004, the United States began implementing the OIF 3 troop rotation. OIF-3 plans call for troops numbers to be reduced from 140,000 to roughly 130,000.

According to documents presented during a HASC hearing on July 7, 2004, US force disposition plans call for a Stryker Brigade to remain stationed in Northern Iraq. The 1st Brigade, 25th Infantry Division, will replace in this role the 3rd Brigade, 2nd Infantry Division. In the North-central sector of Iraq, The 1st Infantry Division will be replaced by the 42nd Infantry Division of the NY National Guard, while II MEF will take over I MEF operations in Western Iraq. The Brigade of the 1st Armored Division attached to the Polish south-central sector, will be replaced by the 2nd Brigade, 10th Mountain. Finally, the 3rd Infantry Division will take over the 1st cavalry Divison in Baghdad. As part of the rotation, OIF units will be deploying 'heavy'.

The number of Army National Guard brigades in Iraq will increase during this rotation from three to five. The rotation will mark a first with a National Guard division headquarters (42nd Infantry Division) assuming, for the first time in Iraq, command active-duty brigades.
