The 321st Sustainment Brigade is a sustainment brigade of the United States Army Reserve.

The 321st Materiel Management Center (MMC) (Theater Support) was activated as the Headquarters and Headquarters Company, 321st Logistical Command Fort Wayne, Indiana, on 27 February 1951, and inactivated on 31 December 1955. In October 1981, the unit was reactivated as the 321st Materiel Management Center (Provisional). The unit was assembled from Detachment 1, 4013th U.S. Army Garrison in Baton Rouge, Louisiana., and 458th Stock Control Company in El Dorado, Arkansas. The 321st MMC became a permanent unit in the Army Reserve on 16 April 1982, under the command of the 377th Theater Army Area Command (TAACOM) in New Orleans, Louisiana. On 20 September 1990, the 321st MMC was mobilized at Fort Polk, Louisiana, during Operation Desert Shield, and arrived in Dhahran, Saudi Arabia on 9 October 1990. Initially, the MMC was assigned the task of logistical management for Third Army (ARCENT). As the theater matured, the MMC managed the prodigious logistics effort necessitated by the flow of massive forces, which enabled the Army to decisively defeat the enemy in 100 hours. The 321st MMC’s outstanding accomplishments resulted in the unit being awarded the Meritorious Unit Commendation. Operation Desert Calm saw the MMC involved in facilitating the deployment of all U.S. Army units back to Europe and the United States. The unit also supported Operation Provide Comfort aimed at helping the isolated Kurdish resistance in Iraq. The 321st MMC received three campaign credits in Southwest Asia during these operations. They are "The Defense of Saudi Arabia", "The Liberation and Defense of Kuwait" and the "Cease Fire".
