According to Title 10 USC, what forces make up the Army?

The correct answer is grounded in how the United States Army is structured as per Title 10 of the United States Code (USC). Title 10 outlines the organization of the Armed Forces, including the Army, and specifies the various components that make up the Army.

The Army comprises one regular Army and two reserve components, specifically the Army National Guard and the Army Reserve. This structure allows the Army to retain a robust and flexible force, capable of meeting both active and reserve needs. The regular Army consists of full-time soldiers on active duty, while the reserve components provide additional manpower and capabilities that can be mobilized in case of national emergencies, conflicts, or during peacetime to assist in various roles.

In contrast to the other options, which do not accurately describe the composition of the Army, this answer reflects the legal framework for Army operations and its organizational structure, highlighting the importance of both active and reserve roles in maintaining national defense.
