How UCMJ Sentencing Rules Apply
Every article page on this site describes punishment in two separate layers. They are related, but they are not the same thing, and neither one is a prediction of what sentence any particular case will receive.
1. Maximum authorized punishment
Part IV of the Manual for Courts-Martial states, for each offense, the most severe punishment that may lawfully be adjudged — for example, the type of punitive discharge, the maximum period of confinement, and the maximum forfeiture of pay. These maximums are also collected in Appendix 12 of the Manual. A court-martial may not impose a sentence greater than the maximum established by law or by the President for that offense. Where the law prescribes a mandatory minimum punishment for an offense, the sentence must include it.
These maximums remain part of the current Manual. They were not replaced by the sentencing-parameter system described below.
Other rules can lower the punishment actually available in a given case — for example, the jurisdictional limits of a special court-martial or a summary court-martial.
2. Sentencing parameters and sentencing criteria
For offenses covered by the newer system, the President has assigned each offense — or each version of an offense — either to an Offense Category (Appendix 12C) or to the list of sentencing criteria offenses (Appendix 12D).
Offense Categories. Each category corresponds to a confinement range (Appendix 12B):
| Offense Category | Confinement range |
|---|---|
| Category 1 | 0–12 months |
| Category 2 | 1–36 months |
| Category 3 | 30–120 months |
| Category 4 | 120–240 months |
| Category 5 | 240–480 months |
| Category 6 | Confinement for life with eligibility for parole |
When an offense is subject to a sentencing parameter, the military judge must sentence the accused for that offense within the applicable parameter, unless the judge finds specific facts that warrant a sentence outside it. A sentence outside the parameter requires a written statement of the factual basis in the record.
Two limits apply to the ranges in the table:
- The authorized maximum still controls. If the maximum confinement authorized for the specific offense is shorter than its category’s upper limit, the shorter period is the recommended maximum confinement for that offense. For example, an offense in Category 1 whose authorized maximum confinement is 3 months has a recommended maximum of 3 months, not 12.
- Special courts-martial. Appendix 12B provides that, at a special court-martial, an offense in Category 3 or higher uses a 12-month confinement parameter, the special court-martial’s jurisdictional maximum; the military judge may impose less confinement upon finding specific facts that warrant it. Separately, Article 19(b) imposes a lower forum limitation when charges are referred to the military-judge-alone special court-martial described in Article 16(c)(2)(A): that court may not adjudge a bad-conduct discharge, confinement for more than six months, or forfeiture of pay for more than six months.
More than one specification. At a general or special court-martial, the military judge determines a term of confinement for each specification of which the accused is found guilty. Under R.C.M. 1002(b)(2), as amended by Executive Order 14130 (2024), the judge also states whether each term runs concurrently or consecutively with the others. The terms must run concurrently in the situations the rule lists, including when each specification involves the same victim and the same act or transaction, and, at a special court-martial, to the extent necessary to keep the total confinement within the court’s jurisdictional maximum.
Sentencing criteria offenses. For offenses listed in Appendix 12D, there is no numbered range. The military judge must instead consider the applicable sentencing criteria in determining the sentence.
Offenses that depend on another offense. Some articles — principals, accessories after the fact, attempts, conspiracy, and certain solicitations — are classified as “dependent on underlying offense”: their treatment follows the offense they relate to.
Death penalty. Sentencing parameters and sentencing criteria do not apply to the determination of whether an offense should be punished by death. Capital cases are sentenced under separate rules.
3. Which set of rules applies
Only one set of sentencing rules applies in a court-martial:
- If the accused is convicted of any offense for which death may be adjudged, the capital sentencing rules apply.
- Otherwise, if the accused is convicted of any offense committed on or before 27 December 2023, the accused is sentenced under the rules that were in effect before 28 December 2023.
- The sentencing-parameter system applies when the accused is convicted only of offenses committed after 27 December 2023. In that case, the sentence is determined by a military judge.
A single case can therefore be sentenced under the older rules even if most of its offenses postdate 27 December 2023.
4. The date of the conduct can matter in other ways
The version of an offense’s elements, definitions, and maximum punishment that applies can also depend on when the conduct occurred, because several articles have been amended or renumbered over time — most significantly by the Military Justice Act of 2016, effective 1 January 2019, and by later changes to the sexual-offense articles. Where an article page describes an earlier version, it labels it as such. The Renumbering Guide explains which article numbers changed meaning.
5. What these figures are not
A maximum punishment is a legal ceiling. A sentencing parameter is a legal framework for the judge. Neither is a forecast of the sentence in any case. Actual sentences depend on the forum, the specific charges and specifications, the findings, any plea agreement, and the aggravating and mitigating circumstances presented.
