In brief: Of 1,836 Marine Corps convictions with a sentence recorded, 293 (16%) had no confinement, with trial dates from 2016 to 2025. Of those 293, 240 (82%) came from a special court-martial. In federal court, 46,079 of 659,036 people sentenced (7%) received probation only in fiscal years 2016 to 2025.
This post uses the U.S. Sentencing Commission's records of 659,036 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.
Which Marine Corps Courts Imposed No Confinement?
Of the 293 no-confinement convictions, 240 (82%) were at a special court-martial. A special court-martial caps confinement at one year and cannot impose a dishonorable discharge. A general court-martial can impose any lawful sentence.
The 82% is a share of the 293 no-confinement convictions. It is not a share of all 1,836 Marine Corps convictions, and it does not say how often special courts-martial ended in confinement.
This forum split is the main difference between the Marine Corps group and the federal group, which has no court with a cap on sentence length.
How Many Marine Corps Convictions Had No Confinement?
The Marine Corps records list 1,836 convictions with a sentence recorded. A total of 293 (16%) had no confinement.
In federal court, the U.S. Sentencing Commission counted 659,036 people sentenced in fiscal years 2016 to 2025. Of them, 46,079 (7%) received probation only, which the data defines as a sentence length of zero, counting alternative confinement. The Marine Corps share of 16% was higher than the federal share.
Did a No-Confinement Sentence Mean No Discharge?
Not always. Among the 258 enlisted members convicted with no confinement, 50 (19%) still received a punitive discharge. A punitive discharge is a bad-conduct discharge or a dishonorable discharge.
A sentence with no confinement can also include a reduction in rank, forfeiture of pay, or a reprimand. The records used here count only whether confinement was adjudged.
Marine Corps Results by Year
The share of Marine Corps convictions with no confinement was 8% in 2017 and 26% in 2025. In between, it was 15% in 2018, 20% in 2019, 10% in 2020, 9% in 2021, 13% in 2022, 23% in 2023, and 24% in 2024.
The 2016 row has only 6 convictions, 2 of which had no confinement, so its percentage is not reported. The federal probation-only share was 6% to 8% in every year.
| Year | Marine Corps convictions | No confinement | Federal: probation only |
|---|---|---|---|
| 2016 | 6 | 2 of 6 | 8% |
| 2017 | 247 | 8% | 8% |
| 2018 | 255 | 15% | 7% |
| 2019 | 202 | 20% | 7% |
| 2020 | 209 | 10% | 7% |
| 2021 | 226 | 9% | 7% |
| 2022 | 164 | 13% | 6% |
| 2023 | 153 | 23% | 6% |
| 2024 | 202 | 24% | 7% |
| 2025 | 172 | 26% | 7% |
What Does the Comparison Show?
The Marine Corps share was higher than the federal share in every year from 2018 to 2025. In 2017, both were the same, at 8%.
The pattern shows the Marine Corps rate changing over the period while the federal rate stayed nearly flat. The records cannot show whether the change reflects different offenses, different charging practices, or something else.
What the Records Cannot Show
The records do not show which offenses led to a sentence without confinement, whether a plea agreement was involved, or what the court considered. The Marine Corps and federal groups also cover different mixes of offenses.
Federal cases are counted by fiscal year and court-martial cases by trial date, so yearly figures line up only roughly.
How We Counted
Marine Corps: courts-martial with a trial date in 2016 to 2025 ending in a conviction with the sentence recorded (1,836). Federal: everyone sentenced in fiscal years 2016 to 2025 (659,036, U.S. Sentencing Commission); "probation only" means a sentence length of zero, counting alternative confinement.
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.
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.
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.
