About Us "CAN DO!"


The 377th Theater Sustainment Command has a dual-mission: 


  • Exercise mission command of the 4th ESC, 143d ESC, 310th ESC, 316th ESC, Deployment Support Command (DSC), the Army Reserve Sustainment Command (ARSC), providing trained and ready units and individuals in support of overseas contingency operations and other global requirements


  • On order the 377th Theater Sustainment Command (TSC)  provides centralized mission command and coordination for operational level sustainment of active component forces responding to catastrophic Homeland Defense(HD)Defense Support of Civil Authorities (DSCA)  and security cooperation operations in the U.S. Northern Command area of responsibility. 

The 377th TSC is assigned to the Army Service Component Command (USARNORTH), and participates in multiple annual exercises which include Vibrant Response, Ardent Sentry, Vigilant Shield and Defense Coordinating Office Certification Exercises.  Additionally, the command coordinates sustainment of contingency operations ranging from presidential inaugurations, State of the Union addresses, U.N. General Assembly meetings and political conventions to complex catastrophes such as hurricanes, earthquakes, wildfires and man-made disasters.   







The 377th Theater Sustainment Command (TSC) is a multifunctional unit that performs a dual mission. The first is mission command of assigned forces in order to provide the U.S. Army Reserve with trained and ready individuals and units that support geographic combatant command requirements. The second mission is to deploy and operate as the senior Army logistics headquarters capable of planning, controlling and synchronizing operational-level Army deployment and sustainment. The 377th TSC has nearly 35,000 Soldiers and Civilians in 33 states. The workforce is made up of approximately 80 percent citizen Soldiers, 10 percent represent the active component and about 10 percent are civilians. It is commanded by a major general (two-star) with six brigadier general (one-star) commanders in charge of subordinate commands across the country.

The unit was activated in July 1942 as Headquarters and Headquarters Company, 12 Port of Embarkation, at Fort Dix, New Jersey. It was then converted, reorganized and redesignated the 12th Port Headquarters and Headquarters Company, and assigned to the Transportation Corps in November 1942. After an inactivation in 1946, the unit was redesignated Headquarters and Headquarters Company, 377th Transportation Major Port, and assigned to the Organized Reserve Corps in November 1948. Two weeks later, the 377th Transportation Major Port was activated in New Orleans. The unit has been a part of the New Orleans community since then.

In September 1950, the 377th was called to Fort Eustis, Virginia, and stayed on active federal service until Oct. 10, 1952. From 1953 to 1963, the 377th remained in a Reserve status and experienced extensive growth and several changes in unit designation.

In December 1965, the unit was redesignated as the 377th Support Brigade under the Army Logistical Concept. On Oct. 16, 1979, it was renamed the 377th Corps Support Command and retained this designation until July 16, 1981, when it was designated as a Theater Army Area Command (TAACOM). On Oct. 1, 1998, the TAACOM wartime mission expanded and the unit designation was changed to the 377th Theater Support Command.

The 377th Theater Support Command was redesignated the 377th Theater Sustainment Command and regionally aligned to U.S. Southern Command in September 2007. Since then, the 377th TSC has generated and globally deployed sustainment forces for multiple missions in support of Operations Enduring Freedom, Iraqi Freedom and New Dawn.  Additionally, the 377th TSC provided earthquake relief in Haiti as part of Operation Unified Response in 2010 and provided assistance to the East Coast in the wake of Hurricane Sandy in 2012.  More recently, the 377th TSC has transitioned to work with U.S. Army North, strategic partners and subordinate units in support of homeland defense, Defense Support of Civil Authorities and Security Cooperation Operations. As the Army transforms, the 377th TSC will continue to lead the way by integrating emerging technology with the best-trained and ready Soldiers to provide sustainment solutions to support any mission.
