Which section of U.S. law outlines the organization and training of the active duty military?

The organization and training of the active duty military is outlined in Title 10 of the U.S. Code. This title specifically addresses the armed forces, setting forth laws related to the organization, staffing, and operational duties of the Army, Navy, Air Force, Marine Corps, and Coast Guard when operating under the Department of Defense. It includes provisions for recruitment, retention, training, and discipline, thereby establishing a comprehensive framework for managing and preparing the active duty military forces.

In contrast, other titles pertain to different aspects or branches of U.S. law. For example, Title 32 focuses primarily on the National Guard and its state role, while Title 14 concerns the Coast Guard and related maritime law, and Title 50 deals with war and national defense aspects relating to national emergencies and other related contingencies. Each of these titles serves distinct purposes and governs specific entities or functions, which is why Title 10 is recognized as the primary law for the structure and operational aspects of the active military.
