An Article 15 in the military is a command disciplinary process, formally called nonjudicial punishment or NJP. Congress created it in Article 15 of the Uniform Code of Military Justice, now codified at 10 U.S.C. § 815. It gives a commander a way to address a minor offense without convening a court-martial.

The name changes among the services. The Army and Air Force commonly say “Article 15,” the Navy and Coast Guard use “Captain’s Mast,” and the Marine Corps also uses “Office Hours.” These labels describe the same basic federal military-justice authority, although each service has its own implementing rules and forms.

Article 15 is command discipline, not a court-martial

The central distinction is the decision-maker and the kind of proceeding. In NJP, a commander evaluates the allegation, decides whether the member committed an offense, and, if so, selects an authorized punishment. A court-martial is a judicial proceeding conducted under the UCMJ and the Rules for Courts-Martial, with a military judge and formal trial protections.

Nonjudicial does not mean informal in the everyday sense or consequence-free. The allegation concerns an offense under federal military law, and an adverse result can affect pay, grade, duties, liberty within military limits, and a member’s service record. But NJP is not a federal criminal conviction, and an Article 15 cannot itself impose a punitive discharge.

The UCMJ describes NJP as punishment for “minor offenses.” The Manual for Courts-Martial explains that deciding whether misconduct is minor depends on factors such as the nature of the offense, the circumstances, the offender’s age, rank, duty assignment, record, and experience, and the maximum sentence available if the matter were tried by general court-martial. An offense ordinarily is not minor when the maximum general-court-martial punishment includes a dishonorable discharge or more than one year of confinement.

The commander controls whether NJP is offered

Article 15 does not give a service member a right to make a commander use NJP. The commander exercises personal discretion over whether the process is appropriate and what punishment, if any, is warranted. A commander may instead use an administrative measure, take no action, or pursue a court-martial through the applicable procedures.

That discretion also explains why “getting an Article 15” is not the punishment itself. The initial notice starts a process. The commander must still consider the information presented and decide whether the alleged offense occurred before punishment may be imposed.

The choice of forum has an important vessel exception

Before punishment is imposed, most members may demand trial by court-martial instead of accepting NJP. Article 15 expressly excludes a member attached to or embarked in a vessel from that statutory choice. The Manual further explains that a demand for trial does not require the government to convene a court-martial; the matter may be disposed of through another lawful option.

Accepting NJP chooses the forum rather than admitting the allegation. A member may accept the proceeding and still deny the offense, present evidence, or explain matters in defense, extenuation, or mitigation. “Defense” addresses whether the member committed the offense; “extenuation” supplies circumstances surrounding it; and “mitigation” supplies reasons for a less severe punishment.

Service procedures set response periods and forms, so an Army Article 15 package does not necessarily use the same timeline or paperwork as an Air Force, Navy, Marine Corps, Space Force, or Coast Guard matter. Official service materials commonly provide for consultation with military defense counsel before the election, but the precise procedural rights and deadlines come from the current governing service rules and the member’s notice.

What happens at an Article 15 proceeding

The usual sequence begins with notice of the alleged offense and the commander’s intent to consider NJP. The member receives an opportunity to review the supporting information available under the governing rules, make an election about the forum when that election exists, and present matters to the commander.

The presentation may address both liability and punishment. It can include oral or written statements and information offered in defense, extenuation, or mitigation. The commander then determines whether the member committed one or more alleged offenses and, if so, which authorized punishment is appropriate.

The Manual for Courts-Martial uses a preponderance-of-the-evidence standard for the commander’s decision. That means the commander must be persuaded that it is more likely than not that the offense occurred. A court-martial, by contrast, may convict only when guilt is proved beyond a reasonable doubt.

Punishment limits depend on rank and command authority

Article 15 lists categories of authorized punishment rather than one fixed penalty. Depending on the circumstances, those categories can include admonition or reprimand, restriction, extra duties, correctional custody for eligible enlisted members, forfeiture or detention of pay, and reduction in grade for eligible enlisted members.

The ceiling changes with several variables. Officers and enlisted members are subject to different categories; some punishments require a commander of a specified grade or one exercising general court-martial jurisdiction; reduction authority depends on the member’s grade and the commander’s promotion authority; and service regulations may impose additional limits. Confinement for up to three consecutive days appears in the statute only for a person attached to or embarked in a vessel.

For enlisted personnel, the statute generally allows a stronger range when the imposing commander is in the grade of major or lieutenant commander or above. That range can include forfeiture of one-half of one month’s pay per month for two months, restriction for up to 60 days, extra duties for up to 45 days, correctional custody for up to 30 days, and authorized reduction in grade. These are statutory ceilings, not automatic outcomes, and they may not all be combined at their individual maximums.

A commander may suspend all or part of an authorized punishment under the governing rules. The UCMJ also permits the imposing officer or a successor in command to suspend, remit, or mitigate an unexecuted portion and, in appropriate circumstances, set aside punishment and restore affected rights, privileges, and property.

An appeal reviews the Article 15 result within the chain of command

A member who considers Article 15 punishment unjust or disproportionate may appeal through the proper channel to the next superior authority. The appeal must be promptly forwarded and decided, although the punishment may continue while the appeal is pending.

The superior authority may leave the result in place or exercise the same powers to suspend, remit, mitigate, or set aside punishment that the imposing commander has. For specified punishments above the thresholds listed in Article 15, the appellate authority must refer the appeal to a judge advocate or, in a Coast Guard matter, a Department of Homeland Security lawyer for advice before acting.

The UCMJ itself does not establish one universal number of days for every service’s appeal submission. Service rules and the notice form supply the operative deadline. For example, current Air Force materials state five calendar days, while other services may use different terminology and procedures.

An Article 15 and a court-martial have different legal consequences

NJP is designed to preserve good order and discipline without a criminal trial. A court-martial can adjudge punishments unavailable at Article 15, including a punitive discharge when authorized, and a court-martial conviction is a criminal conviction. Those differences are why the choice of forum can carry consequences beyond the immediate punishment.

Article 15 also addresses later proceedings arising from the same conduct. Enforcement of NJP does not bar a court-martial for a serious offense growing out of the same act or omission when that offense was not properly punishable under Article 15. If the prior disciplinary punishment is shown at trial, it must be considered when determining the punishment after a guilty finding.

Separate administrative consequences may follow the underlying conduct or the NJP record under service-specific personnel rules. Those personnel actions are separate from the punishments imposed through Article 15 itself.

Article 15 is federal military law, not state criminal procedure

The UCMJ is federal law governing people subject to military jurisdiction. State criminal law does not set the commander’s Article 15 authority, punishment limits, or appeal route. The same event can nevertheless raise separate civilian, state, federal, or administrative issues, and an NJP decision does not by itself resolve those other systems.

Article 15 fits within the broader Uniform Code of Military Justice, while a military trial follows the court-martial framework. Keeping those two paths separate makes the essential point clear: NJP is meaningful military discipline, but it is not simply a smaller criminal trial.
