About the Army
CPT Wallis and Soldiers in the field

Structure

Because the Army is made of such a large number of Soldiers, it must be organized into units, each with its own leaders and reporting structure. Each unit—whether it’s a squad or division—was created to respond to any mission, regardless of size or complexity.

Composition

The Army is made of two major components: Active Duty and Army Reserve.  Enlisted Soldiers, noncommissioned Officers (NCOs), Warrant Officers and Commissioned Officers make up both components.
