1st Theater Sustainment Command

Who We Are


The 1st Theater Sustainment Command (1st TSC) is a two-star Army command made up of nearly 10,000 military, civilian, and contractor personnel. We maintain two headquarters, our main command post at Fort Knox, Kentucky and our operational command post located at Camp Arifjan, Kuwait.

Currently, 1st TSC Soldiers are deployed in over 11 countries around the world - ensuring warfighters have the supplies and transportation capabilities they need to accomplish their missions.


A global sustainment provider, we supply food, fuel, water, transportation, ammunition, building materials, and repair parts. Additionally, we manage the ports, flights, and customs points needed to keep people and equipment moving 24 hours a day, seven days a week.


The 1st TSC also provides adjunct support in the areas of financial management, human resources, humanitarian aid distribution, host-nation engagements, and medical care for troops and civilians within the command.                        




We are a physically and mentally tough, combat-ready organization that thrives in uncertain and complex conditions.

We always expect to win, refuse to fail, and take initiative to accomplish the mission.

We are superbly trained in sustainment operations, have high expectations of each other, and trust our leaders, subordinates, and comrades.


Soldiers with the 1st TSC are in the fight every day, moving what is needed throughout the 20 country, 6-million square mile U.S. Central Command area of responsibility. We support three named campaigns: Operation Inherent Resolve, Operation Freedom’s Sentinel, and Operation Spartan Shield, in addition to a peace-keeping mission supported by our unit, Task Force Sinai, in Egypt.
