First Army Division East is a division of the First United States Army. With its new role, the First Army developed two subordinate multi-component headquarters – one division to support the eastern United States and the other to support the western United States. First Army Division West was activated at Fort Carson, Colorado, and later moved to Fort Hood, Texas. First Army Division East was activated on 7 March 2007, and is headquartered at Fort Knox, Kentucky.

First Army Division East was established by Department of the Army Permanent Order 156-7 to provide training and readiness oversight and mobilization operations for an area of responsibility spanning 27 states and territories east of the Mississippi River. First Army Division East is responsible for mobilizing, training, readiness oversight and deploying the United States' Reserve and National Guard Soldiers, and selected Sailors and Airmen along with members of multiple interagency and governmental entities.
