Title 10 of the United States Code


Title 10 of the United States Code outlines the role of United States Armed Forces.
It provides the legal basis for the roles, missions and organization of each of the services as well as the United States Department of Defense. Each of the five subtitles deals with a separate aspect or component of the armed services.
The current Title 10 was the result of an overhaul and renumbering of the former Title 10 and Title 34 into one title by an act of Congress on August 10, 1956. The provisions of United States Code within Title 10 that are outlined in this article are up to date as of March 13, 2024.
Title 32 outlines the related but different legal basis for the roles, missions and organization of the United States National Guard in the United States Code. Laws regarding the National Guard in federal service are in Title 10, Chapter 1211.
