Which document contains regulations for military courts-martial proceedings?

The Manual for Courts Martial serves as the comprehensive set of regulations governing the procedures for military courts-martial proceedings. It outlines the rules and legal standards that must be adhered to during these judicial processes, ensuring that service members receive fair treatment under the law. This document provides detailed instructions on various aspects of court-martial, including the types of offenses, procedures for prosecution and defense, and the rights of the accused, all essential for maintaining discipline and justice within the military framework.

The other choices, while related to military operations and legal structures, do not specifically address the procedural regulations of courts-martial. Specifically, a Field Manual is designed for operational guidance and tactical procedures, while the Naval Operations Handbook focuses on naval operational practices. The Uniform Code of Military Justice establishes the overall legal framework for military justice, but does not provide the detailed procedural rules that the Manual for Courts Martial offers.
