The Uniform Code of Military Justice (UCMJ) is a federal law that establishes the legal framework for the military justice system in the United States. It applies to all members of the U.S. Armed Forces, including active duty, reserve, and National Guard personnel. The UCMJ outlines various offenses, procedures for courts-martial, and the rights of service members, ensuring discipline and order within the military. The UCMJ is essential for maintaining good order and discipline among military personnel. It covers a wide range of offenses, from minor infractions to serious crimes, and provides a structured process for investigating and prosecuting these offenses. The UCMJ also includes provisions for appeals and protections for service members, ensuring fairness in the military justice system.
