America’s Army Reserve — the most capable, combat-ready, and lethal federal reserve force in the history of the Nation.

Globally engaged for more than 15 consecutive years of war, the Army Reserve has been, and continues to be, an essential element of the Total Army and the Joint Force, meeting high operational tempo demands, providing predictable operating and generating forces to Combatant Commands as required. Since 2001, Army Reserve Soldiers have been mobilized more than 335,000 times and deployed across the globe, to include every major combat zone.

Meeting ongoing defense and security demands requires continued access to, and reliance upon, the skills, capabilities, and experience of a ready Army Reserve. A federal operational Army Reserve force saves the Army money; reduces the demand for Active Army capabilities; mitigates Army capability shortfalls, and preserves the readiness of the Total Army. Army Reserve depth and scalability meets current and anticipated requirements of the Combatant Commands; achieves a cost-efficient balance by using the strengths and capabilities of each component; and provides a sufficient base of trained, equipped and ready Soldiers, leaders and units from which the Active Component may draw upon when needed. Most importantly, a ready and operational Army Reserve provides the critical enabling capabilities that combat forces rely upon to win America’s wars.

When Unified Land Operations are required, the Nation integrates and synchronizes all of America’s military services, but it can do so only with the support of the Army Reserve, which provides critical early entry and set the theater capabilities. These include Petroleum Pipeline and Terminal Operations, Biological Identification Detachments, Broadcast Operation Detachments, Civil Affairs, Theater Engineer Commands, Medical Logistics, and others crucial to opening and sustaining major operations.

Command authority of the Army Reserve rests under a single individual who is both the Chief of the Army Reserve and the Commanding General of United States Army Reserve Command. This streamlined command structure ensures unity of command and unity of effort in the resourcing, training, and accessing of the Army Reserve.

This enables support of every Army Service Component Command and worldwide Combatant Command with an Army Reserve footprint in all 50 States, five territories, and more than 30 countries. The Army Reserve is uniquely designed from the ground up to meet the needs of the Joint Force under this single unified command authority.

The Chief of Army Reserve is the principal advisor on Army Reserve matters to the Secretary and Chief of Staff of the Army. The Office of the Chief of Army Reserve plans, prepares, resources and manages the force and is responsible for the justification, defense, and execution of the Personnel, Operations and Maintenance, and Construction budgets.

The Army Reserve provides trained, equipped and ready Soldiers and cohesive units to meet the Nation’s requirements, at home and abroad.

• Logistics
• Civil Affairs
• Military Police
• Medical
• Military Information Support Operations (information operations and cyber operations)
• Postal and Personnel Management
• Chemical
• Transportation
• Legal Support
• Chaplain

The Army Reserve is structured to manage specialized capabilities, including those not present anywhere else in the Joint Force, such as:
• Sustainment capabilities required for major operations, but too expensive to maintain on active duty, such as theater-level transportation, engineer, and logistics units.
• Career fields that are in high demand in the civilian sector, and difficult to retain on active duty, such as medical, legal, engineering and cyber skills.


In addition to a broad spectrum of low-density and high demand enabling units throughout its force, the following commands/capabilities exist only in the Army Reserve: 

• Theater engineer commands
• Civil Affairs commands
• Medical minimal care detachments
