In brief: Junior enlisted service members (E-1 to E-4) convicted of manslaughter under Article 119 had a median adjudged confinement of 60 months, based on 27 convictions with trial dates from 2016 to 2025. That compares with a median prison term of 63 months for 737 people sentenced in federal court in fiscal years 2016 to 2025. Within the court-martial group, sentences after a guilty plea were longer than in contested cases.
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 series, which builds on Military Moves Toward Sentencing Guidelines to Mirror the Federal System. How the numbers were built: How the Federal Comparison Data Was Built.
Guilty Pleas and Contested Cases in the Junior Enlisted Group
Of 23 convictions with a plea recorded, 14 (61%) were guilty pleas. The median confinement after a guilty plea was 76.5 months, from 14 cases with confinement. In contested cases that ended in conviction, it was 28.5 months, from 8 cases with confinement.
A contested case is one where the accused pleaded not guilty to at least one charge. The records cannot show why the guilty-plea median was higher, and the contested group has only 8 cases with confinement.
In federal court, the pattern ran the other way. The median prison term was 63 months after a guilty plea and 90 months after a trial, based on 51 people convicted at trial.
All Junior Enlisted Convictions
The records list 27 junior enlisted convictions for manslaughter. By service, there were 10 in the Army, 5 in the Air Force, 4 in the Navy, and 8 in the Marine Corps.
Confinement was part of the sentence in 26 of 27 cases (96%). The median adjudged confinement was 60 months, or 5 years, and a quarter of the sentences were 95.9 months or more. A punitive discharge was imposed on 26 of the 27 (96%), with 16 dishonorable discharges and 10 bad-conduct discharges.
All 27 convictions (100%) were at a general court-martial.
| Courts-martial: Junior Enlisted (E-1 to E-4) | Federal court, FY2016–FY2025 | |
|---|---|---|
| Convictions or people sentenced | 27 | 737 |
| Sentenced to confinement or prison | 96% | 96% |
| Median confinement or prison | 60 months | 63 months |
| A quarter received this or more | 95.9 months | 108 months |
| Pleaded guilty | 14 of 23 with a plea recorded (61%) | 93% |
| Mandatory minimum applied | See the caveats | 4% |
Change Over Time and Other Ranks
The median confinement for trials in 2016 to 2019 was 63 months, from 6 cases with confinement. For trials in 2020 to 2025, it was 60 months, from 20 cases. The medians are close, but the earlier group is small.
The records for all ranks show 38 convictions, a median confinement of 60 months, and confinement in 92%. The junior enlisted median matches the median for all ranks.
The Federal Comparison Group
Federal records have no rank. The 737 people were sentenced under guideline §2A1.3 (voluntary manslaughter) or §2A1.4 (involuntary manslaughter). Prison went to 708 (96%), and 24 (3%) received probation only.
A quarter of the prison terms were 108 months or more, and a quarter were 35.8 months or less. The median was 63 months, or 5.2 years. Guilty pleas ended 686 of the cases (93%), and a mandatory minimum prison term applied to 28 people (4%).
What the Comparison Does Not Show
Rank is the rank at trial as listed in the court-martial record. The federal data has no matching field, and court-martial records have no criminal history field, which is the nearest federal measure of record.
Court-martial sentences are as adjudged at trial, before any clemency or appeal. Federal prison terms are those imposed, not time served. The records cannot show the facts of any case, so the groups should not be treated as matched.
How We Counted
Courts-martial with trial dates in 2016 to 2025 ending in a conviction for manslaughter (Article 119) where the accused was junior enlisted (e-1 to e-4) (27). Federal: 737 people sentenced under guideline §2A1.3 (voluntary manslaughter) or §2A1.4 (involuntary manslaughter) (U.S. Sentencing Commission). Federal records have no rank; criminal history is the nearest federal measure of record, and courts-martial have no criminal history field.
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.
