55th Sustainment Brigade
55th Theater Support Command - Materiel Management Center (MMC)

The 55th TSC (MMC) consists of forward and rear elements. This organization operates under a split-based concept with a forward element that is in support of deployed theater units while maintaining a rear element in support of non-deployed units. When required, this organization deploys Material Management Teams (MMTs) capable of providing limited Corps Materiel Management Center (CMMC) forward functions and immediate communications with all elements prior to the establishment of the theater communications network.

The 55th Materiel Management Center (MMC), Theater Support Command (TSC), (Multi-Component) was activated on 17 October 2000 by combining the 55th MMC in Fort Belvoir, Virginia and the 6th Support Center, MMC's, in Taegu, Korea.

The 55th MMC is now Multi-Component - part Reserve and part Active Duty unit. The active duty component is based at Camp Henry, South Korea and the reserve component is at Fort Belvoir, Virginia. The mission on the 55th is to Perform integrated supply and maintenance management at Theater level for the Army Service Component Theater Support Command on all classes of supply (less classified maps, medical, and COMSEC) and for all assigned and designated maintenance activities.

The 55th MMCs Lineage began with the creation of the 435th Highway Transport Command (HTC) in 1954. In 1963, the 435th HTC was reorganized and redesignated as the 300th Transportation Group (TG). In 1969, the 300th TG was redesignated as the 300th Field Army Support Command. On 30 November 1977, the 300th Field Army Support Command was reorganized and redesignated as the 55th MMC. The 55th MMC was assigned to the 310th Logistical Command at the John Singleton Mosby United States Army Reserve Center, Fort Belvoir, Virginia.

When the 310th Logistical Command moved from Fort Myer, Virginia to a warehouse in the heart of Old Town Alexandria, Virginia the new home was designated the Mosby USAR Center" in honor of Colonel John Singleton Mosby, also known as 'The Gray Ghost' who was a native of Alexandria. Colonel Mosby's Rangers operated primarily in the Northern Virginia area often disrupting the logistical supply lines of the Union Army. During the late 1950's, his exploits received wide publicity as the result of the weekly television series "The Gray Ghost". The series was based on the book "Gray Ghosts and Rebel Raiders" by Virgil Carrington Jones. When the 310th moved to the Army Reserve Center at Fort Belvoir, Virginia in 1975, the building was dedicated as the John Singleton Mosby United States Army Reserve Center (JSMUSARC).)

For two decades, the 55th MMC's training prepared the soldiers to augment the 200th Theater Army Materiel Management Center (TAMIMC) in Zweibruecken, Germany. This paired the reserve soldiers with their counterpart active duty personnel and units with whom they would be involved if there were to be war in Europe. The 55th MMC soldiers were present on an Active Tour (AT) when the Berlin Wall came down. Soldiers from the 55th MMC have served with distinction in a wide variety of missions, including individuals who have been called to active duty to support the Army's objectives in Operation Desert Shield and Storm" (Persian Gulf) and "Operation Restore Democracy" (Haiti).

From 8 July 1996 through 3 February 1997, a seventy-person cell from the 55th MMC was mobilized for active duty to support the United Nations Peacekeeping mission in Bosnia. The unit's mission provided logistical and materiel management support to the soldiers of the U.S. Army's 1st Armor Division, 1st Infantry Division and other elements enforcing the peace in Bosnia-Herzegovina. A secondary mission was to assist those support elements based in Kapsovar and Taszar, Hungary. These locations became the main staging bases for all U.S. forces entering and leaving the Balkan theater of operations. Mission requirements were such that the 55th MMC soldiers found themselves stationed throughout the theater of operations in Bosnia, Croatia and Hungary. The 55th MMC functioned as a materiel management center for all supplies at the corps level during its deployment.

Adapting to changes since the end of the Cold War, the 55th MMC was reassigned from the 310th Theater Army Area Command (TAACOM) to the 99th Regional Support Command on 16 April 2000.

Unit level maintenance (operator/organization) (10/20 series) is maintenance performed on tactical equipment by individual operators, who are assigned to vehicles and equipment, and other organizational manpower. Equipment and manpower are identified on each unit's Modified Table of Organization and Equipment (MTOE). At this level, Commanders are responsible for the resources, maintenance capabilities and readiness of assigned MTOE personnel. OPTEMPO funds are provided each Major Subordinate Command (MSC) through the PBG distribution process. If units have the capabilities, the next higher level, or direct support level work can be performed. Direct Support maintenance (DS - 30 level) is maintenance being performed on tactical equipment by divisional MTOE manpower. Although backup support to unit level maintenance is authorized, the primary purpose is to service mobile weapon systems and conduct other related logistical and inspection functions. Funding is provided by OPTEMPO funds and distributed to the MSC. Depot-level maintenance (50 level) provides peacetime, combat ready, technical support and backup to DS and GS maintenance units. In wartime, the theater commander assumes control of all depot-level work. Based on capability and capacity, depot-level repairs are authorized at the MSC-K. Payment for depot-level maintenance is provided by the 6th Support Center and reimbursable customers

In Korea, "MORE" stands for EUSA's management of redistributable equipment (MORE) program. It's a semiannual, cyclical program that assists commanders in accounting for and redistributing excess equipment at all levels throughout the major Army command (MACOM). The MORE program, which was established by Lieutenant General Richard F. Timmons, EUSA's Commanding General, on 26 December 1995, is executed in four timed phases, with one entire cycle completed in a 150-day period, or two cycles completed each year. During the major subordinate command (MSC) phase, which also is allotted 30 days for completion, commanders ensure completion of all actions outlined in the brigade phase and report all remaining excess requiring further action to the theater's materiel management center, the 6th Support Center.
