What document outlines the Uniform Code of Military Justice?

The Uniform Code of Military Justice (UCMJ) is the correct answer because it is the foundational document that establishes the legal framework for the military justice system. The UCMJ outlines the rights of service members, the types of conduct that are subject to military discipline, and the procedures for courts-martial and other disciplinary actions. It is a comprehensive set of laws that govern the armed forces and is essential for maintaining order and discipline within the ranks.

Other choices might reference relevant guidance or regulations within the Department of Defense or Army, but none encapsulate the complete legal code as the UCMJ does. The Department of Defense Manual may provide broader policies, the Manual of Military Justice could refer to various interpretations or applications of the UCMJ, and the Army Regulations Handbook may contain specific rules and policies, but these do not serve as the codified legal statute itself. Hence, relying on the UCMJ is critical for understanding the military justice system and the legal rights and responsibilities of service members.
