Strictly speaking, military law does not classify offenses as felonies or misdemeanors the way civilian criminal law does. So the most accurate answer is that an Article 90 violation is not labeled a felony within the military justice system, because that system does not use that label at all. That said, willfully disobeying a superior commissioned officer under Article 90 of the Uniform Code of Military Justice (UCMJ) is a serious offense that can be punished at a level comparable to a civilian felony and that can carry consequences treated as felony-equivalent outside the military. Understanding the difference between the formal classification and the practical effect is important.
How the military categorizes offenses
Civilian criminal codes typically sort crimes into felonies and misdemeanors, usually based on the maximum authorized term of imprisonment, often using one year as the dividing line. The UCMJ does not work this way. It defines punitive offenses by article, sets a maximum punishment for each, and sorts cases by the level of court-martial, summary, special, or general, rather than by a felony or misdemeanor tag. There is no statutory provision in the UCMJ that declares a given article a felony. So when someone asks whether an Article 90 violation is a felony, the cleanest answer is that the military system simply does not use that terminology.
This matters because a misleading yes or no can create confusion. It is not that Article 90 is a minor matter. It is that the felony or misdemeanor framework belongs to civilian law and is not the way the military formally organizes its offenses.
What Article 90 prohibits
Article 90 addresses two related kinds of conduct: striking or assaulting a superior commissioned officer, and willfully disobeying a lawful command of a superior commissioned officer. The disobedience branch is the one most often discussed. Its elements require that the accused received a lawful command from a certain officer, that the officer was the accused’s superior commissioned officer, that the accused knew the officer held that status, and that the accused willfully disobeyed the lawful command.
The word willfully is central. Article 90 targets deliberate defiance, an intentional refusal to obey a known, lawful order. A member who tries to comply but fails, who misunderstands the order, or who is genuinely unable to carry it out has not willfully disobeyed. Mere failure to perform a routine duty, or violation of a standing …
