Who Does UCMJ Apply To?

The word ‘military’ in the name is the key to understanding who falls under the Uniform Code of Military Justice. The list of personnel who are governed by the UCMJ includes, but is not limited to:

  • All military members (active, reserve, retired)
  • Members of quasi-military organizations including Public Health Service when the members serve with Armed Forces
  • Military prisoners
  • Prisoners of war
  • Some civilians

In the subchapter I – General provisions, Article 2 specifically states who is subject to the code, and who is not.


The President of the United States is required by law, as acting commander-in-chief of the Armed Forces, to write regulations to implement military law. The President writes the rules by issuing an executive order called Manual for Courts-Martial, or the MCM.

The MCM sets forth rules and regulations for military court-martials and specifies maximum punishments for each military offense that is listed in the subchapter X – Punitive articles.

UCMJ Rules For Judicial Punishment

Military court-martials are the most harsh sanctions under military law. A court-martial conviction is on the same level as a federal conviction and can result in jail time, or even a punitive discharge (dishonorable discharge, fines, reduction in rank, etc.).

The Uniform Code of Military Justice divides court-martials into three categories:

  1. Summary Court-Martial
  2. Special Court-Martial
  3. General Court-Martial

The category depends on the rank of the accused and the severity of the offense.

1. Summary Court-Martial

Summary court-martials are the least serious out of the three options. They usually handle minor incidents and they are relatively rare these days. It is like non-judicial punishment proceedings (subchapter III, Article 15), only the summary court-martial can result in a federal conviction.

There is no jury, and while it is allowed, it’s not required to provide the accused with a defense lawyer, except in the Air Force. A commissioned officer in the pay grade of O-3 or above presides over summary court-martials. The maximum punishment is considerably less severe than that of a general or special court-martial, and it includes:

  • Confinement for 30 days, or hard labor without confinement for 30 days
  • Forfeiture of ⅔ pay for one month
  • Reduction to the lowest pay grade (E-1)

In some cases, like if the accused is above the pay grade of E-4, punishment may not be imposed, except reduction to the next lowest pay grade.

2. Special Court-Martial

Special court-martial is similar to the misdemeanor court in civilian courts of law, and it has jurisdiction over all personnel charged with any UCMJ offense. It is used for punishments of medium severity.

Special court-martials consist of a military judge, defense and prosecuting attorneys, and a jury of at least three military members. The panel, or jury, usually consists of commissioned officers and warrant officers, but in case the accused is an enlisted member, he can demand that at least a third of the panel be enlisted members. There is also the option for the accused to dismiss the panel and be tried by the judge alone.

The maximum punishment includes a combination of:

  • Confinement for 12 months
  • Forfeiture of ⅔ pay for 12 months
  • Reduction to the lowest pay grade (E-1)
  • A bad conduct discharge

3. General Court-Martial

General Court-Martial is the most serious type of military courts, and it is reserved for the most serious offenses, including murder, rape, robbery, etc. It has jurisdiction over all personnel charged with any UCMJ offense.

General Court-Martial proceedings can only be convened by the President, Secretary of Defense, the commanding officer of a major military installation, and by a general or a flag officer.

It includes a military judge, prosecuting and defense attorneys, and a jury of at least five members. Similar to the special court-martial, if the accused is an enlisted member, he can request that at least a third of the panel be enlisted members. Furthermore, the accused can dismiss the panel and choose to be tried by the judge alone. The accused can select to be represented by a civilian lawyer at his own expense.

The maximum punishment imposed by the general court-martial can be any sentence authorized by the Manual for Military Courts-Martial, including the death sentence.

UCMJ Rules For Non-Judicial Punishment

These rules are addressed in the subchapter III of the Uniform Code of Military Law. Non-judicial punishment is the most common type of proceeding under the military justice system. When a military member commits an offense, the commanding officer may decide to offer him proceedings under the Article 15 of the subchapter III.

The proceedings are similar to the summary court-martials. The difference is that the commanding officer can act as judge and jury, and the proceedings don’t result in a criminal record. The accused can turn down the Article 15 and demand a trial by court-martial, except if he is aboard a ship at sea.

Does the UCMJ Take Precedence Over Civilian Law?

In short, the answer is no, the UCMJ does not take precedence over civilian law. Subchapter II – Apprehension and Restraint states that if a crime violates both military and civilian state law, the accused military member can be tried by the military court and the civilian court.
