Which statement best describes the scope of the UCMJ?

• A. It governs military conduct under U.S. law
• B. It governs state laws
• C. It governs civil court procedures
• D. It governs international treaties

Answer: (A)

The UCMJ exists to govern military discipline and criminal offenses for members of the U.S. armed forces, as a federal framework that operates under U.S. law. It defines what counts as an offense in the military context, and it sets up the procedures for trying and punishing service members (courts-martial and non-judicial punishment). Because of that, its reach is over military personnel and military-related conduct, not over civilian state laws, civilian court procedures, or international treaties. State laws handle civilian crime, civil courts handle civil procedures, and international treaties are governed by international law. So describing it as governing military conduct under U.S. law accurately captures its scope.
