About the Army
CPT Wallis and Soldiers in the field


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.


The Army is made of two major components: the Active Duty and Army Reserve. Those who serve in either component are Enlisted Soldiers, Non-Commissioned Officers (NCOs), Warrant Officers or Commissioned Officers.
