The Army Reserve is one of three components in the Army, along with Active Duty and Army National Guard. The Army Reserve has more than 2,000 units in the United States, Guam, the Virgin Islands, Puerto Rico and Germany, each one trained in a specialized skill and ready to support Army missions around the world.

At the top of the Army Reserve’s chain of command is a three-star General with two distinct roles. The first is Chief, Army Reserve (CAR). The CAR reports to the Chief of Staff of the Army and represents the Army Reserve in policy and planning discussions with the Army, the Department of Defense and Congress. The CAR is responsible for all Army Reserve Soldiers, even those who report directly to the Army.

The General’s second role is Commanding General (CG) of the U.S. Army Reserve Command (USARC). The CG of USARC reports to Army Forces Command and is responsible for the staffing, training and readiness of most Army Reserve units in the continental United States and Puerto Rico .

Office of the Chief Army Reserve (OCAR)
The Chief, Army Reserve (CAR) has a staff of functional advisors who develop and execute Army Reserve plans, policies and programs, plus administer Army Reserve personnel, operations and funding. These advisors are part of OCAR, which is located in the Pentagon in Washington, DC.

U.S. Army Reserve Command (USARC)
USARC commands all Army Reserve units in the continental United States and Puerto Rico except for Civil Affairs and Psychological Operations, which report directly to the Army. USARC is responsible for the staffing, training, management and deployment of its units to ensure their readiness for Army missions. Below USARC in the command structure are Regional Readiness Commands, Divisions and other major commands that report directly to USARC.

Regional Readiness Commands (RRCs)
RRCs provide resource, logistics and personnel management services to all Army Reserve units within their region. There are 11 RRCs serving the continental United States and Puerto Rico.

Divisions: Institutional Training (DIV-IT) and Training Support (DIV-TS)
Divisions are responsible for training both Active Duty and Reserve Soldiers throughout the United States. There are two types of training Divisions: Institutional Training Divisions (DIV-IT), which run schools, and Training Support Divisions (DIV-TS), which train Soldiers in the field.

Direct Reporting Commands (DRC)
DRCs are large commands that report directly to USARC and are responsible for organizing, planning and executing missions for the Army. DRCs cover areas such as engineering, medical and signal (communications).

Army Direct Reporting Units (DRU)
A number of Army Reserve units are assigned to commands other than the U.S. Army Forces Command (FORSCOM) and therefore do not report to USARC. These units are DRUs to the Army, and include Special Operations Commands as well as Army Reserve Commands outside the continental United States.

7th Army Reserve Command (ARCOM)
The 7th ARCOM is located in Heidelberg, Germany, and reports to the U.S. Army European Command (USAREUR).

9th Regional Readiness Command (RRC)
The 9th RRC is located at Fort Shafter in Hawaii and reports to the U.S. Army Pacific Command (USARPAC).

Special Operations
Civil Affairs and Psychological Operations units report to the U.S. Army Special Operations Command (USASOC) through the U.S. Army Civil Affairs and Psychological Operations Command (USACAPOC). Army Reserve units account for 96% of USACAPOC’s force.
