CASCOM is responsible for training more than 180,000 students annually through 541 courses taught by the Ordnance, Quartermaster and Transportation schools, Soldier Support Institute and Army Sustainment University.

CASCOM is a major subordinate element of the Training and Doctrine Command which trains and educates Soldiers and Civilians, develop and integrates capabilities, concepts and doctrine, and executes functional proponency to enable the Army's Sustainment Warfighting Function.

The U.S. Army Combined Arms Support Command (CASCOM) at Fort Gregg-Adams, Virginia, had its origins in a 1950 Project VISTA study, which, among other recommendations, proposed that the Army set up a separate and independent command to formulate and test new concepts.

In further support of this reform, separate branch agencies were organized for each of the technical services (Quartermaster, Ordnance, Transportation, Adjutant General, Chaplain, Civil Affairs, Medical Service, and Military Police) and operated as tenants at bases where their respective schools were located.

Additionally, within each branch school, separate departments of combat development and doctrinal expertise existed.

The Judge Advocate General and Finance Schools were added in 1964, while Civil Affairs was transferred to the Combat Arms Group.

[2] In a 1966 reorganization, the CSSG at Fort Lee assumed responsibility for developing all support elements for the Army in the field.

Five CSSG directorates were combined into three: Personnel and Administration; Program and Budget; and Doctrine, Organization, Materiel and Evaluation.

Additionally, in 1975, TRADOC instructed the Logistics Center to establish a mission capability in force restructuring, the importance of which has continued to the present.

With this increased authority, Lieutenant General Robert Bergquist set out to enhance the position of Combat Service Support with TRADOC by promoting the concept of multifunctionalism.

The success of this initiative led to the subsequent redesign of logistics support commands and units at the division and echelons-above-division level.

the Soldier Support Center was disestablished and the Soldier Support Institute was moved to Fort Jackson, South Carolina, following closure of Fort Benjamin Harrison due to the 1991 Base Realignment and Closure (BRAC) legislature.

In the early 1990s, multi-functional training for Army Captains was advanced by the creation of the Combined Logistics Officers Advanced Course (CLOAC) at the Army's Logistics Management College (ALMC) at Fort Lee, which included company command multifunctional leadership and staff training.

The Logistics Captains Career Course at Army Sustainment University is the enduring evolution of this effort.

[4] Subsequent to BRAC, and the establishment of TRADOC's Center of Excellence model, the Sustainment Center of Excellence (SCoE) was established at CASCOM to oversee and coordinate the functions of the five sustainment branches: Ordnance, Quartermaster, Transportation, Finance, and Adjutant General.

Post leaders assembled a group called "Task Force Eagle," which spent the next four months supporting OAR.
