The Army Reserve is classified under which component?

The Army Reserve is classified under COMPO 2. This classification is part of the United States Army's structure that categorizes its components based on active duty and reserve affiliation. The Army Reserve is considered a federal reserve force, providing support and additional forces to the active component when required, but it operates primarily as a reserve unit that can be called upon in times of need.

COMPO 1 represents the active component, which is the full-time force in active duty service. COMPO 3 consists of the Army National Guard of the United States, which operates under both state and federal authority. COMPO 4 refers to other specialized components that are not classified under the main reserve and active categories.

By understanding these classifications, it becomes clear why the Army Reserve is designated as COMPO 2, reflecting its role and structure within the larger framework of the Army.
