List of formations of the United States Army during the War on Terrorism

After the end of Operation Desert Storm/Shield, the US Army inactivated many units. The units fighting the War on Terrorism are the survivors of the "Peace Dividend". While additional fighting brigades are being created, no additional deployable higher headquarters units are planned.
