Article 91 of the Uniform Code of Military Justice punishes insubordinate conduct toward a warrant officer, noncommissioned officer, or petty officer. It covers three distinct behaviors: striking or assaulting such a person, willfully disobeying that person’s lawful order, and treating that person with contempt or being disrespectful in language or deportment. Because the offense reaches enlisted members and the structure of military discipline, the question of what raises the severity of a sentence comes up often. The answer has two layers. First, the offense itself contains built-in elements that change the ceiling on punishment. Second, separate sentencing rules allow the government to present aggravation evidence that pushes a sentence toward the higher end of whatever range applies.
Severity Built Into the Offense Itself
Article 91 does not carry a single maximum punishment. The ceiling depends on what the accused did and the status of the person involved. Striking or assaulting a warrant officer is treated most seriously, followed by striking or assaulting a superior noncommissioned or petty officer, then striking or assaulting other noncommissioned or petty officers. Willful disobedience of a lawful order carries its own range, and contempt or disrespect sits at the lower end. In this sense, the facts that elevate the maximum are part of the charge rather than separate aggravators. Moving from disrespect to disobedience to physical assault changes the legal ceiling before any evidence about circumstances is even heard.
The status of the victim matters as well. The term “superior” noncommissioned or petty officer carries weight because the rank relationship and the duty context can raise the authorized punishment compared with conduct directed at a peer-level noncommissioned officer.
The “In the Execution of Office” Element
A recurring factor that affects Article 91 cases is whether the warrant officer, noncommissioned officer, or petty officer was acting in the execution of their office at the time of the conduct. This element is significant because it goes to whether the offense is fully made out under the more serious framing. Conduct directed at a noncommissioned officer who is carrying out official duties is treated differently from conduct that occurs in a purely private setting unrelated to military function. Counsel on both sides pay close attention to this point because it can move a case between charging theories and affect exposure.
Aggravation Evidence at Sentencing
Even after findings, the punishment is not fixed at a single number. Military sentencing procedure allows the prosecution to present matters in aggravation. Under the Rules for Courts-Martial governing presentencing, aggravation evidence may include evidence of the financial, social, psychological, and medical impact on any person who was the victim of the offense, as well as evidence of significant adverse impact on the mission, discipline, or efficiency of the command that results directly and immediately from the accused’s conduct.
This last category is especially relevant to Article 91. Insubordination is, by its nature, an offense against good order. When a noncommissioned officer is struck in front of a formation, or when an order is openly defied during an operation, the harm to unit discipline can be presented as aggravation. Evidence that the conduct undermined a leader’s authority, disrupted a mission, or required other members to intervene speaks directly to the impact the rules allow the government to show.
Victim Input and Prior Service
Military presentencing also gives a qualifying victim the right to be reasonably heard. A noncommissioned officer who was assaulted may provide a statement describing the effect of the offense. This is separate from the government’s aggravation evidence and is governed by its own procedural rules, but it can shape how a sentencing authority views the seriousness of the conduct.
The accused’s record cuts both ways. The prosecution may introduce evidence of prior convictions and information about the character of the accused’s prior service. A history of disciplinary problems can reinforce a request for a heavier sentence, while strong prior service supports mitigation. None of these are unique to Article 91, but they operate in every such case.
The Effect of Recent Sentencing Reform
The framework for assigning punishment has changed in recent years. Offenses committed before late December 2023 are generally measured against the traditional maximum punishment tables, while offenses committed on or after that date fall under a revised sentencing structure introduced by the Military Justice Act of 2023. Because the date of the offense controls which framework applies, anyone evaluating exposure in an Article 91 case must first confirm when the conduct occurred. The categories of aggravation evidence remain available under both systems, but how a final sentence is calculated may differ.
Practical Takeaways
For a service member facing Article 91 allegations, several factors realistically drive severity. Physical violence is treated more seriously than disobedience, which in turn is treated more seriously than disrespect. The rank and official status of the person involved affects the ceiling. Whether that person was performing official duties at the time can change the charging theory. At sentencing, proof that the conduct damaged unit discipline, disrupted a mission, or harmed the victim can move the result toward the top of the available range, while a clean record and credible mitigation can pull it down.
Because the analysis turns on specific facts, including the date of the offense and the exact charged behavior, anyone facing these allegations should consult qualified military defense counsel before deciding how to proceed. The difference between a disrespect theory and an assault theory, and the strength of the government’s aggravation evidence, can change the outcome substantially.

Military law also changes over time.
