Soldier Support Institute

The Soldier Support Institute (SSI) at Fort Jackson, South Carolina is a U.S. Army organization and major subordinate command of the Combined Arms Support Command and part of the Sustainment Center of Excellence (SCoE). It is also part of the Training and Doctrine Command (TRADOC).

Train and educate soldiers and civilians in Financial Management, Human Resources Support, Music Support, Postal Operations, and Recruiting and Retention; develop complementary concepts, doctrine, organizations, and materiel to strengthen an all volunteer U.S. Army as America's force of decisive action.

The SSI consists of three major schools: Adjutant General, Financial Management, and the Recruiting and Retention Schools. It also includes the Noncommissioned Officer Academy, the 369th Adjutant General Battalion, and the Training Support Battalion.

The Adjutant General and Financial Management Schools are “home” to their respective Army branches, the Adjutant General's Corps and the Finance Corps. The two branch schools offer the Basic Officer Leadership Course for newly commissioned lieutenants and the Captain's Career Course for first lieutenants and captains in their third or fourth year of commissioned service. The School Commandants are the proponents for their branches and oversee the development of Doctrine, Organizations, Training, Leader Development, Materiel, and Personnel within their corps (Active and Reserve Components). The Soldier Support Institute's Concepts Development & Integration Directorate and Training Development Directorate assist the Commandants with these tasks. Both schools frequently assemble Mobile Training Teams (MTTs) to go to specific geographical regions to train soldiers.

The Adjutant General School also includes the Bands Program, and The Army School of Music (see United States Armed Forces School of Music) currently located at Joint Expeditionary Base Little Creek-Fort Story (JEBLCFS,) Virginia. The Interservice Postal School is also an element of the Adjutant General School which trains enlisted Soldiers and noncommissioned officers from all of America’s military services in modern postal operations. The Adjutant General School also conducts Basic Warrant Officer and Advanced Warrant Officer courses within human resources management.
