In most cases the answer is no, not by personal choice. Nonjudicial punishment, the proceeding authorized by Article 15 of the Uniform Code of Military Justice, is a military disciplinary process, and the default expectation is that a service member appears in the uniform prescribed by the commander or the local command. Civilian attire is generally worn only when the member is no longer in a duty status that requires a uniform, when a command specifically authorizes it, or in limited circumstances such as certain Reserve or retired contexts. Because the rules come from service and local command policy rather than the UCMJ itself, the precise answer depends on the branch and the command. This article explains how that works and why the question matters.
What nonjudicial punishment is
Nonjudicial punishment, commonly called NJP, Article 15, captain’s mast in the Navy and Coast Guard, or office hours in the Marine Corps, is a tool that lets a commander address minor misconduct without a court-martial. Article 15 of the UCMJ authorizes commanding officers to impose limited punishments after notifying the member of the alleged offense, the evidence, and the member’s rights. The member ordinarily has the right to be heard, to present matters in defense and mitigation, to have a spokesperson, and, in most situations, to refuse NJP and demand trial by court-martial instead.
NJP is administrative and disciplinary in character rather than a criminal trial. That distinction matters for the dress question, because the proceeding is conducted within the command’s normal military environment and is governed by command and service regulations on appearance and conduct.
Why uniform is the default
A service member on active duty in a duty status is expected to be in the uniform of the day or the uniform the command prescribes. An NJP proceeding is a formal command function, and commanders routinely direct that the member appear in a specified uniform, often the service or dress uniform appropriate to the occasion. The reason is straightforward. The member is still subject to military authority, the proceeding takes place during duty, and appearance standards apply to official command business just as they apply to other formations and ceremonies.
Because uniform wear during NJP is controlled by the commander and by service appearance regulations, a member usually cannot simply decide to show up in civilian clothes. The commander sets the standard, and failing to meet a lawful appearance directive could itself be a disciplinary issue.
When civilian clothes may be appropriate
There are recognized situations where civilian attire is the norm rather than the exception. A member who is not in a uniform-required status may appear in civilian clothing. This can include reservists who are not in a drilling status at the time, members who have been separated from active duty but remain subject to limited jurisdiction, or members whose medical or administrative status excuses them from wearing the uniform.
A command can also authorize civilian clothes for a particular proceeding. Commanders have discretion over the conduct of NJP within the bounds of service regulation, and some will permit or even direct civilian attire depending on the setting and the member’s status. The key point is that civilian dress is generally a matter of command authorization or duty status, not a personal entitlement the member can assert over the commander’s instructions.
Branch-specific policy controls the details
Because the UCMJ and the Manual for Courts-Martial set the framework for NJP but leave appearance to regulation, the specific dress rules differ by service. The Army, Navy, Marine Corps, Air Force, Space Force, and Coast Guard each maintain their own regulations and command policies that govern uniform wear, appearance at official functions, and the conduct of nonjudicial punishment proceedings. Local commands frequently issue their own instructions that prescribe the uniform for mast, office hours, or an Article 15 hearing.
For that reason, a member should never assume a general rule applies to a particular case. The controlling answer comes from the member’s own service regulation and the convening command’s policy. A judge advocate or area defense counsel can confirm what uniform or attire the specific proceeding requires.
Why the dress question is more than cosmetic
Appearance at NJP is not only about formality. Showing respect for the proceeding by complying with the prescribed uniform reflects the seriousness of the process and avoids creating an avoidable disciplinary problem on top of the underlying allegation. A member who disregards a lawful uniform directive risks giving the impression of defiance, which is unhelpful when the member is asking the commander to view the matter favorably in mitigation.
At the same time, the member retains the substantive rights that matter most at NJP, including the right to consult counsel, to examine the evidence, to present a defense, and in most cases to refuse NJP and elect trial by court-martial. Those rights are independent of what the member wears.
Bottom line
Service members are generally not free to choose civilian clothes for an NJP proceeding. The default is the uniform prescribed by the commander or service regulation, because NJP is an official military disciplinary function conducted during duty. Civilian attire becomes appropriate mainly when the member is not in a uniform-required status, such as certain Reserve or post-service situations, or when the command specifically authorizes it. Since these rules flow from branch regulations and local command policy rather than from the UCMJ directly, a member facing NJP should confirm the required attire with the command and with defense counsel rather than relying on a general assumption.
