9th Regional Readiness Command
9th Regional Support Command
The 9th Regional Readiness Command mission is to provide combat ready forces that meet the peacetime and wartime requirements of the Warfighting CINC, and to provide command and control of USAR Forces in the USARPAC Area of Responsibility. During peacetime, 9th RSC falls under the command of U.S. Army Pacific (USARPAC).
In 1961, IX Corps became a separate headquarters of U.S. Army Pacific. The 9th Regional Support Command [9th RSC] in Hawaii was designated HQ IX Corps (Augmentation) and was organized on January 16, 1962. At that time it was an integral part of the active Army's IX Corps, and participated in command post exercises with the corps for its annual training.
On April 27, 1987, the organization in Hawaii was re-designated HQ IX Corps (Reinforcement). Effective December 1, 1991, this organization was re-designated again as HQ IX Corps (Reinforcement/9th ARCOM). Effective October 1, 1995, the command in Hawaii was re-designated HQ 9th U.S. Army Reserve Command, following the inactivation of IX Corps at Camp Zama, Japan in September 1995. When IX Corps was deactivated, the 9th Theater Army Area Command was activated in its place in Japan.
In late 2003 all Regional Support Commands were re-designated to Regional Readiness Commands.
