9th Regional Support Command

The mission of the 9th Mission Support Command is to execute Army Reserve Command and Control (C2) in accordance with Title 10 responsibilities in the US Army, Pacific (USARPAC) area of responsibility in order to support mission requirements from USARPAC and the US Army Reserve Command (USARC). The 9th Mission Support Command also provides contingency operations mission support to Joint Task Force - Homeland Defense as required. The 9th Mission Support Command as of 2010, was comprised of approximately 3,500 Army Reserve Soldiers and 160 civilians throughout the Pacific to include Hawaii, Alaska, American Samoa, Japan, Korea, Guam and Saipan.

The mission of the 9th Regional Readiness Command mission was to provide combat ready forces that met the peacetime and wartime requirements of the Warfighting Commander in Chief (CINC), and provided command and control of US Army Reserve (USAR) Forces in the USARPAC area of responsibility. During peacetime, 9th Regional Readiness Command would have fallen under the command of USARPAC.

In 1961, IX Corps became a separate headquarters of US Army Pacific. The 9th Regional Support Command in Hawaii was designated as Headquarters, IX Corps (Augmentation) and was organized on 16 January 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 27 April 1987, the organization in Hawaii was redesignated as Headquarters, IX Corps (Reinforcement). Effective 1 December 1991, this organization was redesignated again as Headquarters, IX Corps (Reinforcement/9th ARCOM). Effective 1 October 1995, the command in Hawaii was redesignated Headquarters, 9th US Army Reserve Command, following the inactivation of IX Corps at Camp Zama, Japan in September 1995. When IX Corps was inactivated, the 9th Theater Army Area Command was activated in its place in Japan.

In late 2003, all Regional Support Commands were redesignated as Regional Readiness Commands. The 9th Regional Readiness Command was subsequently redesignated as the 9th Mission Support Command.
