LINEAGE:
"TO DO FOR COUNTRY"
The 79th Theater Sustainment Command provides trained and ready logistics units for worldwide operations and deployment. The 79th TSC’s operational designation in Sept. 16, 2017 makes it the newest of the Army’s Theater Sustainment Commands and one of only two in America's Army Reserve, with units that span locations dispersed across 24 states.

Activated in 2009 as the 79th Theater Sustainment Command, its specialized capabilities support both Defense Support of Civil Authorities and early entry/set-the-theater requirements.

As the operational command posts of a TSC, Theater Sustainment Commands plan, coordinate, synchronize, monitor, and control operational-level sustainment for Army Service Component Commands, joint task forces, joint forces commands, and multinational forces throughout the world.

The 79th traces its lineage back to the 79th Infantry Division, activated in August 1917.
 
The 79th fought in the Meuse-Argonne campaign during the closing months of World War I, earning the nickname “Cross of Lorraine” for its defense of France. After inactivating in June 1919, the 79th was re-activated in June 1942; two years before reporting to the Port of Embarkation at Camp Myles Standish, Massachusetts in April 1944. Three months later the unit disembarked on Utah Beach, Normandy, June 12-14.

Following stiff enemy opposition during multiple campaigns of World War II, where three Soldiers from the division were awarded the Medal of Honor, the 79th went on to become an occupation force in the Dortmund, Sudetenland, and Bavarian areas successively.
