Where can the authority for military readiness and administration be found?

The authority for military readiness and administration is primarily found in Title 10 of the United States Code. Title 10 outlines the legal framework for the role of the armed forces, specifying the organization, functions, and responsibilities of the military, including training, administration, and readiness requirements. It serves as the foundational statutory authority for the armed services, detailing how they are to be maintained, organized, and utilized in both peacetime and wartime.

In contrast, Executive Orders serve as directives from the President but may not encompass the complete range of aspects related to military readiness or administration as defined in Title 10. NATO Regulations pertain to military guidelines and procedures for NATO member nations but do not govern U.S. military authority specifically. Department of Defense Directives provide guidance and policy for the operations of the Department of Defense but do not themselves constitute the legal authority that is outlined in Title 10. Thus, Title 10 is the most comprehensive and authoritative source for military readiness and administration.
