United States Army Combined Arms Support Command is a major subordinate command of United States Army Training and Doctrine Command (TRADOC) headquartered at Fort Gregg-Adams, Virginia. It serves as the United States Army's proponent for logistics, supply chain management, and sustainment doctrine, training, and force development. The command integrates combat service support capabilities across the Department of Defense to ensure operational readiness for the Total Force.

History

The command was established in 1990 as part of a post-Cold War reorganization, consolidating several Army Materiel Command and Forces Command logistics schools under TRADOC. Its creation aimed to unify sustainment training and doctrine development following lessons from operations like Operation Just Cause and in preparation for Operation Desert Storm. Initially headquartered at Fort Lee, its location was central to the Army Logistics University and other key institutions. The command has evolved through subsequent conflicts, including Operation Enduring Freedom and Operation Iraqi Freedom, adapting doctrine for counterinsurgency and large-scale combat operations. In 2023, following the redesignation of its home installation, its headquarters was officially listed at the renamed Fort Gregg-Adams.

Organization

The command is led by a major general and includes a Deputy Commanding General and a Command Sergeant Major. Its structure integrates several key directorates and subordinate centers, including the Sustainment Center of Excellence, which oversees branch-specific schools. Key components include the Ordnance School, the Quartermaster School, and the Transportation School, each responsible for their respective military occupational specialties. The command also oversees the Army Logistics University and the Combined Arms Support Command Sustainment Battle Lab, which focuses on future concepts and wargaming. It works closely with Army Futures Command on Next Generation Combat Vehicle and soldier modernization efforts.

Mission and functions

Its primary mission is to develop adaptive sustainment leaders, refine agile doctrines, and design integrated capabilities to enable Army readiness. As the functional proponent for logistics, it writes and updates critical field manuals and Army techniques publications governing supply, maintenance, transportation, and distribution operations. The command manages the Doctrine, Organization, Training, Materiel, Leadership and Education, Personnel, Facilities and Policy (DOTMLPF-P) process for all combat service support functions. It supports joint and combined operations by aligning Army sustainment with U.S. Transportation Command, Defense Logistics Agency, and NATO partners. It also validates tables of organization and equipment for sustainment brigades and battalions.

Training and doctrine

The command executes training through its Sustainment Center of Excellence and the Army Logistics University, which provides professional military education from basic officer and non-commissioned officer courses to advanced studies. It oversees the Captains Career Course and the Command and General Staff College's sustainment electives at Fort Leavenworth. Training emphasizes modern battlefield challenges, integrating lessons from the War in Afghanistan and Multi-domain operations concepts. The Combined Arms Support Command Sustainment Battle Lab experiments with emerging technologies like artificial intelligence, autonomous resupply, and predictive logistics. Doctrine development is continuous, with recent publications focusing on contested logistics in environments challenged by Chinese or Russian capabilities.

Commanders

Commanders have typically been major generals with extensive logistics and operational backgrounds. Notable past commanders include General Dennis L. Via, who later commanded Army Materiel Command; General Gustave F. Perna, who later served as Chief Operating Officer for Operation Warp Speed; and General Stephen R. Lyons, who later commanded U.S. Transportation Command. The current commander is MG Mark T. Simerly, who previously served as the Director for Logistics on the Joint Staff.

Subordinate units

Key subordinate units and schools fall under the Sustainment Center of Excellence. These include the U.S. Army Ordnance School at Fort Gregg-Adams, responsible for maintenance and munitions; the U.S. Army Quartermaster School at Fort Gregg-Adams, responsible for supply, field services, and petroleum and water; and the U.S. Army Transportation School at Fort Gregg-Adams, responsible for mobility and distribution. The Army Logistics University consolidates professional military education for all logistics branches. Other elements include the Combined Arms Support Command Sustainment Battle Lab and the Fielded Force Integration Directorate, which manages new equipment training.
