Which provision provides the legal basis for the roles, missions, and organization of each of the services as well as the Department of Defense, guiding the structure and operations of the U.S. Armed Forces?

• A. Command Strategy
• B. Title 10, US Code (Armed Forces)
• C. Strategic guidance
• D. 5-0 Joint Planning Operations

Answer: (B)

The binding legal framework that defines the roles, missions, and organization of each service as well as the Department of Defense is Title 10 of the United States Code. This statute lays out the structure of the armed forces, assigns responsibilities to each service, and establishes how the DoD is organized and operated to recruit, train, equip, and deploy forces. It provides the statutory authority behind the chain of command and the overall arrangement of military power, shaping how the services are designed and how they work together to carry out national defense.

Other terms describe planning processes or policy guidance rather than establishing the legal foundation. Strategic guidance and similar planning concepts influence how forces are used, but they do not create the statutory framework that defines the services and their organization. The remaining phrasing about joint planning operations refers to planning processes, not the formal legal basis for the services and DoD.
