Which document contains the procedures for military justice in the U.S.?

The correct document that contains the procedures for military justice in the U.S. is The Manual for Courts Martial (MCM). This manual outlines the rules and procedures governing courts-martial, including the rights of service members, types of courts-martial, and the processes involved in the prosecution of military offenses. It serves as the primary operational guide for the conduct of military justice, detailing how various aspects of the military legal system are to be implemented.

While the Uniform Code of Military Justice (UCMJ) establishes the legal foundation of military law and outlines offenses that can be tried under military jurisdiction, it does not itself provide the procedural guidelines for how those laws are to be applied in practice. Instead, the MCM operationalizes the UCMJ by providing comprehensive procedures that military legal personnel must follow. Thus, it is essential for proper military legal proceedings and serves as the framework for applying military justice in specific cases.
