**In brief:** The median adjudged confinement for manslaughter convictions at courts-martial was 60 months, based on 38 convictions under Article 119 with trial dates from 2016 to 2025\. In federal court, the median prison term was 63 months, based on 737 people sentenced in fiscal years 2016 to 2025\. The medians are close, but the court-martial group is small and the sets of cases are not the same.

Updated November 2, 2026 · Sources: U.S. Sentencing Commission and Federal Judicial Center, fiscal years 2016–2025 · Military Trial Results

This post uses the U.S. Sentencing Commission's records of 737 people sentenced in federal court in fiscal years 2016 to 2025, compared with court-martial results from this site's Military Trial Results data (updated November 2, 2026). Acquittals and dismissals come from a second source, the Federal Judicial Center's records of 753,808 federal defendants whose cases ended in fiscal years 2016 to 2025\. It is part of the [Federal Prosecution Analysis](https://www.bodiesburied.com/trends/federal/) series, which builds on [Military Moves Toward Sentencing Guidelines to Mirror the Federal System](https://www.bodiesburied.com/trends/military-sentencing-guidelines-federal-system/). How the numbers were built: [How the Federal Comparison Data Was Built](https://www.bodiesburied.com/trends/federal-data-methodology/).

## Medians Compared

The court-martial median of 60 months is 5 years. The federal median of 63 months is 5.2 years. A quarter of court-martial sentences were 95.9 months or more, and a quarter of federal prison terms were 108 months or more.

In the federal data, a quarter of the prison terms were 35.8 months or less. The court-martial records give no matching figure for the lower end in this comparison.

Confinement was part of the sentence in 35 of the 38 court-martial convictions (92%). Prison went to 708 of the 737 federal defendants (96%), and 24 (3%) received probation only.

| Pleaded guilty                     | 20 of 33 with a plea recorded (61%) | 93%                          |
| Mandatory minimum applied          | See the caveats                     | 4%                           |

## The Court-Martial Group

The 38 convictions were spread across the services: 12 in the Army, 7 in the Air Force, 8 in the Navy, and 11 in the Marine Corps. Of the 37 enlisted members convicted, 33 received a punitive discharge (89%). There were 20 dishonorable discharges and 13 bad-conduct discharges.

Nearly all of the convictions were at a general court-martial: 37 of 38 (97%).

Service medians ranged from 36 months in the Navy to 69 months in the Army. Each service holds 12 convictions or fewer, so those differences can change with a single case.

| Service      | Convictions, 2016–2025 | With confinement | Median confinement | Punitive discharge (enlisted) | Guilty pleas (where recorded) |
| ------------ | ---------------------- | ---------------- | ------------------ | ----------------------------- | ----------------------------- |
| Army         | 12                     | 100%             | 69 months          | 92%                           | 91%                           |
| Air Force    | 7                      | 7 of 7           | 60 months          | 7 of 7                        | 2 of 6                        |
| Navy         | 8                      | 6 of 8           | 36 months          | 6 of 8                        | 4 of 7                        |
| Marine Corps | 11                     | 91%              | 62.5 months        | 90%                           | 4 of 9                        |

## Guilty Pleas and Contested Cases

Guilty pleas were less common at courts-martial than in federal court. A plea was recorded for 33 convictions, and 20 (61%) were guilty pleas. In federal court, 686 of 737 people (93%) pleaded guilty and 51 were convicted after a trial.

The systems show opposite patterns on sentence length. At courts-martial, the median confinement was 60 months after a guilty plea, from 19 cases, and 30 months in contested cases that ended in conviction, from 11 cases. In federal court, the median prison term was 63 months after a guilty plea and 90 months after a trial.

A contested case is one where the accused pleaded not guilty to at least one charge. The federal trial group also includes people who pleaded guilty to some counts and went to trial on others.

## Federal Sentences Against the Guideline Range

Federal judges sentence against an advisory guideline range, and 45% of manslaughter sentences were within it. Sentences above the range were given to 30%. Another 12% were below the range at the government's request, and 13% were below it without one.

A mandatory minimum prison term applied to 28 people (4%). Supervised release followed prison for 693 (94%), with a median term of 36 months. Restitution was ordered for 363 (49%).

Of the people sentenced, 57% were in the lowest criminal history category. Court-martial records have no criminal history field.

## Changes Over the Period

Court-martial median confinement was 63 months for trials in 2016 to 2019, from 6 cases, and 60 months for trials in 2020 to 2025, from 29 cases. The federal yearly medians ranged from 41 months in 2018 to 72 months in 2025.

The number of people sentenced federally ranged from 38 in 2020 to 110 in 2024.

| Fiscal year | People sentenced | Median prison | Pleaded guilty |
| ----------- | ---------------- | ------------- | -------------- |
| 2016        | 68               | 60 months     | 96%            |
| 2017        | 73               | 60 months     | 96%            |
| 2018        | 61               | 41 months     | 97%            |
| 2019        | 74               | 63 months     | 95%            |
| 2020        | 38               | 51 months     | 89%            |
| 2021        | 56               | 60 months     | 96%            |
| 2022        | 79               | 70 months     | 92%            |
| 2023        | 85               | 70 months     | 91%            |
| 2024        | 110              | 60 months     | 86%            |
| 2025        | 93               | 72 months     | 96%            |

## What the Records Cannot Show

The federal group covers voluntary manslaughter under guideline §2A1.3 and involuntary manslaughter under §2A1.4\. The court-martial group covers Article 119 convictions and does not separate voluntary from involuntary. The groups may differ in the conduct involved, and the records do not show the facts of any case.

Court-martial sentences are as adjudged at trial, before any clemency or appeal. Federal prison terms are those imposed, not time served. Acquittals and dismissals are in neither count.

### How We Counted

Courts-martial: convictions for manslaughter (Article 119) with trial dates in 2016 to 2025 (38). Federal: everyone sentenced in fiscal years 2016 to 2025 under guideline §2A1.3 (voluntary manslaughter) or §2A1.4 (involuntary manslaughter) (737), from the U.S. Sentencing Commission's individual data files.

Federal fiscal years run from October 1 to September 30\. No person, judge, or lawyer is identified in any of these records.

### What to Keep in Mind

**Who is in each set of numbers.** The federal sentencing numbers come from the U.S. Sentencing Commission. They count only people who were convicted and sentenced in federal district court. People whose cases were dismissed or who were acquitted are not in them. The military numbers come from court-martial results, which include acquittals. To compare acquittal or dismissal rates, the federal side uses a different source: the Federal Judicial Center's case data, which counts every defendant whose case ended.

**Different cases reach each system.** Federal prosecutors bring a narrow set of cases. In fiscal year 2024, immigration and drug trafficking cases were 59% of everyone sentenced in federal court (36,664 of 61,678). Many crimes that the military prosecutes, such as most assaults, most sexual assaults between adults, and drug use, are usually state crimes for civilians and reach federal court only in special situations, such as on federal land or in Indian Country. A federal case and a court-martial for the same crime can involve different kinds of facts.

**Time periods.** Federal numbers are by federal fiscal year (October 1 to September 30), based on the sentencing date. The military numbers are by trial date. Neither source has the date of the offense, so a change in law shows up in either data set gradually.

**Offense categories do not line up exactly.** Each comparison uses a federal offense group chosen to match the military article as closely as possible (see the crosswalk). Some matches are close; others are partial. The post says which federal guideline or statute was used and why it is not an exact match.

**No parole in federal prison; credit for good conduct.** Federal prison has no parole for crimes committed on or after November 1, 1987\. A federal prisoner can earn up to 54 days of good conduct credit for each year of the sentence the judge imposed, which is about 15%. Some federal prisoners can also earn First Step Act time credits, but many offenses make a person ineligible. The numbers in this post are the sentences judges imposed, not the time people actually served.

**Military confinement credit and parole.** For military sentences adjudged after 2004, good conduct time is 5 days for each month of confinement, about 16%. Military prisoners can also earn up to 8 more days a month for work and programs and up to 2 days a month for special acts, with a limit of 15 days a month in total. Military prisoners can be considered for parole by their service's clemency and parole board. The military numbers in this post are the confinement adjudged at trial, not the time served.

**Military sentences include punishments federal sentences do not.** A court-martial sentence can include a punitive discharge (bad-conduct discharge, dishonorable discharge, or dismissal for officers), reduction in rank, and forfeiture of pay. These have no federal counterpart. A comparison of months of confinement leaves them out. A short confinement term combined with a dishonorable discharge is a heavier sentence than the months alone show.

**Federal supervised release.** Most federal prison sentences are followed by a term of supervised release that the judge sets as part of the sentence. A person who violates it can be sent back to prison. A court-martial cannot sentence anyone to supervision after release. Military parole and mandatory supervised release are decided later by a board, not by the judge at trial.

**Who decides the sentence, and under what rules.** Federal judges sentence every federal case. They must calculate the Sentencing Guidelines range, which is advisory, and must impose any mandatory minimum the statute requires unless an exception applies. In courts-martial, the accused could choose sentencing by members until the rules changed. For cases in which every guilty finding is for an offense committed after December 27, 2023, a military judge sentences alone, within sentencing parameters. Courts-martial tried in 2024 and later include both old-rule and new-rule cases, and the data cannot tell them apart.

**How life sentences and "time served" are counted.** In the federal numbers, a life sentence is counted as 470 months, and any other sentence longer than 470 months is counted as just under 470 months. A sentence of "time served" is counted as one day (0.03 months). Averages are affected by these rules; medians much less.
