The United States Army in Operation IRAQI FREEDOM May 2003-January 2005

Appendix F
US Army Units in Operation IRAQI FREEDOM

Order of Battle: May 2003–January 2005

The following order of battle depicts the US Army units at battalion level and above that participated in Operation IRAQI FREEDOM (OIF) between May 2003 and January 2005. This 18-month period included two major troop rotations—OIF I and OIF II; accordingly, this order of battle is divided into two sections. Not all unit deployments fit neatly into these two rotation periods. Task Force Olympia, for example, deployed to Iraq in late 2003; however, that unit is placed in the OIF II portion of this order of battle. Units that arrived in Iraq between November 2004 and January 2005 as part of the troop reinforcement for the national elections are not included in this order of battle.

Task organization of Army formations in OIF during this period was dynamic, particularly at division echelon and below. This order of battle captures habitual command relationships, but recognizes headquarters often shifted battalions and brigade combat teams to meet immediate operational requirements. At times, company-level units from two or more divisions were joined together to form ad hoc task forces—those temporary organizations are not included.


(Combined Joint Task Force–7, built around V Corps Headquarters, replaced CFLCC as Coalition military headquarters in Iraq on 15 June 2003)
