311th Signal Command (Theater)
In September 2006, the 311th Signal Command (Theater) was relocated to Fort Shafter, Hawaii as part of its realignment from association with the Eighth US Army in Korea to US Army Pacific in Hawaii. Previously, the 311th Signal Command (Theater) had been a Direct Reporting Command of the United States Army Reserve Command located at Fort Meade, Maryland. It was commanded by a Major General.
Prior to 2006, the 311th Signal Command (Theater) had had 2 missions in the Pacific. It was firstly a direct deploying unit, and upon mobilization would have deployed to either Fort Shafter, Hawaii, or to the Republic of Korea, depending on the situation involved. If deployed to Korea, it would have served as the communications component of the Eighth United States Army (EUSA), the Army component of United States Forces Korea (USFK). In either instance, the mission was to serve as a Theater Signal Command-Army, the senior Army communications headquarters in the theater. This mission included communications management responsibility for all deployed Army Echelons Above Corps (EAC) signal forces in theater and operation and maintenance responsibilities for EAC communications.
The 311th Signal Command (Theater) was first constituted on 26 January 1944 in the Army of the United States as Headquarters, 3112th Signal Service Battalion. The Battalion was activated on 1 February 1944 at Fort Monmouth, New Jersey. It was reorganized and redesignated on 7 June 1945 as Headquarters and Headquarters Company, 3112th Signal Service Battalion. During the Second World War, the Battalion participated in 5 campaigns: Normandy, Northern France Rhineland, Ardennes-Alsace, and Central Europe. It was subsequently inactivated on 5 December 1946 in Germany.
While inactive, the unit was redesignated on 27 March 1952 as Headquarters and Headquarters Company, 311th Signal Group, and allotted to the Organized Reserve Corps. This Group was activated on 10 April 1952 at Baltimore, Maryland. The Organized Reserve Corps as a whole was redesignated on 9 July 1952 as the Army Reserve, to which the unit remained assigned. The unit was reorganized and redesignated on 26 April 1954 as Headquarters and Headquarters Detachment, 311th Signal Group. It was inactivated on 20 February 1963 at Baltimore, Maryland.
The unit was redesignated on 16 June 1996 as Headquarters and Headquarters Company, 311th Signal Command, and activated at Fort George G. Meade, Maryland.
The US Army Signal Command designated the Army Reserve's 311th Theater Signal Command as the executive agent for the Grecian Firebolt Exercise that occured between 10 and 31 July 1999. Grecian Firebolt was an annual communications exercise, sponsored by the USASC located at Fort Hauchuca, Arizona. The exercise provided theater signal commands with the resources to establish communications networks and validate proficiency of their mission essential tasks. The 311th Theater Signal Command, with the support of US Army Reserve Command (USARC) and the National Guard Bureau (NGB), used the GF99 exercise to provide all available Reserve and Active Component units aligned to the Pacific Command area of responsibility, with a means for command and control of operations. Grecian Firebolt was to provide connectivity to units in the Continental US (CONUS), the Pacific Command (PACOM), and the Republic of Korea (ROK).
As executive agent, the 311th Theater Signal Command had command and control over all participating signal units. The 311th Theater Signal Command was also provided signal support staff to USFK and EUSA. Exercise participants included active Army, Army Reserve and Army/Air National Guard Signal units. The exercise reflected the Army's total force integration initiative, with Reserve Component units training with their active counterparts. Signal units during GF99 provided communications connectivity to the various locations of several major annual training exercises, such as Golden Medic by the 3rd Medical Command, Golden Kastle by the 372nd Engineer Group, Global Patriot by the National Guard Bureau, and Summer EX by the EUSA in Korea. Throughout the GF99 exercise, signal connectivity extended to more than 27 different locations at home and overseas. Units deployed in phases, validating whether their planning efforts would lead to a successful assessment of their mission capabilities. Such validation was to ensure that, when called to serve, the communications resources could provide the connectivity necessary for command and control during deterrence and conflict.
The location of the Command's Headquarters was changed on 16 September 2006 to Fort Shafter, Hawaii.
