Glossary

Terms used throughout this site’s UCMJ punitive article pages, defined once here instead of repeated on every page.

Aggravating and mitigating circumstances

Facts a court-martial considers in deciding the sentence within the punishment the law allows. Aggravating circumstances tend to support a more severe sentence and mitigating circumstances a less severe one. Neither the maximum authorized punishment nor a sentencing parameter stated on an article page predicts the sentence in a particular case.

Appendix 12, 12B, 12C, and 12D

Appendices to the Manual for Courts-Martial dealing with punishment. Appendix 12 collects the maximum authorized punishments stated in Part IV. Appendix 12B sets the confinement range for each Offense Category. Appendix 12C assigns each offense, or each form of an offense, to an Offense Category, to the sentencing criteria list, or to “dependent on underlying offense.” Appendix 12D lists the sentencing criteria offenses. Appendices 12B through 12D were added by Executive Order 14103 in 2023. See How UCMJ Sentencing Rules Apply.

Bad-conduct discharge

A punitive discharge that applies only to enlisted persons and may be adjudged by a general or special court-martial, where the maximum punishment for the offense authorizes it.

Charge and specification

A charge identifies the UCMJ article allegedly violated; a specification states the specific facts alleged. Which article and which form of an offense is charged determines the elements that must be proved and the punishment that applies.

Court-martial

The military trial in which a person subject to the UCMJ is tried. There are three types. A summary court-martial is the least formal and cannot adjudge a punitive discharge. A special court-martial ordinarily may not adjudge death, dismissal, a dishonorable discharge, or confinement for more than one year (Article 19(a)). When charges are referred to the military-judge-alone special court-martial described in Article 16(c)(2)(A), Article 19(b) further bars a bad-conduct discharge and limits confinement and forfeiture of pay to six months. A general court-martial can adjudge any punishment authorized for the offense, including, where authorized, death. The type of court-martial can limit the punishment available in a case, separately from the punishment authorized for the offense.

Dependent on underlying offense

The Appendix 12C classification for offenses whose sentencing treatment follows another offense — for example, attempts, conspiracy, principals, accessories after the fact, most solicitations, and certain forms of domestic violence and injury to an unborn child.

Dishonorable discharge

The most severe punitive discharge for enlisted persons and for warrant officers who are not commissioned. It may be adjudged only by a general court-martial.

Dismissal

The punitive separation of a commissioned officer, commissioned warrant officer, cadet, or midshipman. It may be adjudged only by a general court-martial, and under the Manual it may be adjudged for any offense of which such a person is found guilty, regardless of the maximum punishment stated for the offense.

Forfeiture of pay and allowances

A punishment that takes away pay (and, for total forfeitures, allowances). Part IV states either “forfeiture of all pay and allowances” or a partial forfeiture, such as “two-thirds pay per month” for a stated number of months.

Manual for Courts-Martial (MCM)

The executive order implementing the UCMJ, issued and amended by the President. Part IV states, for each punitive article, the statutory text, the elements, an explanation, the maximum authorized punishment, and a sample specification. This site cites the 2024 edition.

Maximum authorized punishment

The most severe punishment that may lawfully be adjudged for an offense, as stated in Part IV of the Manual — the type of punitive discharge, the forfeiture, and the maximum confinement. It remains part of current law and is not replaced by the sentencing-parameter system.

Offense Category

One of six numbered groups (Appendix 12C) to which an offense, or a form of an offense, is assigned for sentencing parameters. Each category corresponds to a confinement range in Appendix 12B: 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), and Category 6 (confinement for life with eligibility for parole).

Recommended maximum

When the maximum confinement authorized for an offense is shorter than the upper limit of its Offense Category, that shorter period is the recommended maximum confinement for the offense. For example, an offense in Category 1 with an authorized maximum of 3 months has a recommended maximum of 3 months.

Sentencing criteria offense

An offense listed in Appendix 12D. It has no numbered confinement range; the military judge instead considers the applicable sentencing criteria in determining the sentence. Sentencing parameters and criteria do not apply to the decision whether to impose death.

Sentencing parameter

The confinement range for an offense’s Offense Category. When the sentencing-parameter system applies, the military judge must sentence within the applicable parameter unless the judge finds specific facts that warrant a sentence outside it, and must then state those facts in writing on the record. The system applies only when every offense of which the accused is convicted was committed after 27 December 2023; if any offense was committed on or before that date, the rules in effect before 28 December 2023 apply. See How UCMJ Sentencing Rules Apply.

Terminal element

Every offense under Article 134 (the General Article) requires proof of a terminal element, which expresses the clause of Article 134 that applies: for clause 1, that the accused’s conduct was prejudicial to good order and discipline in the armed forces; for clause 2, that it was of a nature to bring discredit upon the armed forces; and for clause 3, that the offense charged was a crime or offense not capital. More than one clause may be alleged, but proof of one is enough. The enumerated Article 134 offenses on this site are charged under clause 1, clause 2, or both. See the Article 134 hub.

UCMJ (Uniform Code of Military Justice)

The federal statute, codified at 10 U.S.C. Chapter 47, that establishes the military justice system for the U.S. armed forces. Articles 77 through 134 are the punitive articles covered on this site.
