The U.S. Army's Command Structure and Mission

Organization

Understanding the Army's Structure

Organization

The Army, as one of the three military departments (Army, Navy and Air Force) reporting to the Department of Defense, is composed of two distinct and equally important components: the active component and the reserve components. The reserve components are the United States Army Reserve and the Army National Guard.

Regardless of component, the Army conducts both operational and institutional missions. The operational Army consists of numbered armies, corps, divisions, brigades, and battalions that conduct full spectrum operations around the world. The institutional Army supports the operational Army. Institutional organizations provide the infrastructure necessary to raise, train, equip, deploy, and ensure the readiness of all Army forces. The training base provides military skills and professional education to every Soldier—as well as members of sister services and allied forces. It also allows the Army to expand rapidly in time of war. The industrial base provides world-class equipment and logistics for the Army. Army installations provide the power-projection platforms required to deploy land forces promptly to support combatant commanders. Once those forces are deployed, the institutional Army provides the logistics needed to support them.

Without the institutional Army, the operational Army cannot function. Without the operational Army, the institutional Army has no purpose.
