Uniform Code of Military Justice (UCMJ) is a federal law enacted by Congress that governs the military justice system. Its provisions are contained in United States Code, Title 10, Chapter 47.

Article 36 of the UCMJ allows the President to prescribe rules and procedures to implement the provisions of the UCMJ. The President does this via the Manual for Courts-Martial (MCM) which is an executive order that contains detailed instructions for implementing military law for the United States Armed Forces.

The UCMJ varies in significant ways from the civilian justice system of the United States. The full code is available to consult online in detail.
