In brief: At Camp Pendleton, 24 of 27 Marine Corps obstruction of justice convictions (89%) included confinement, and the median adjudged term was 14 months. In the Southern District of California, 12 of the 18 people sentenced under guideline §2J1.2 (67%) received prison, with a median prison term of 18 months. Those federal cases come from the entire district, not from the base, and most did not involve service members.
This post uses the U.S. Sentencing Commission's records of 18 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.
Confinement at Camp Pendleton Was More Common, but Shorter
Marines convicted of obstruction at Camp Pendleton were confined more often than people sentenced for obstruction in the surrounding federal district: 89% compared with 67%. The length was another matter. The median confinement at Camp Pendleton was 14 months, while the district's median prison term was 18 months.
The upper end of each range was close. A quarter of the Camp Pendleton sentences were 26.5 months or more. In the district, a quarter of prison terms were 24.8 months or more.
Court-martial sentences in this post are as adjudged at trial, before clemency or appeal. Federal prison terms are as imposed, not as served.
How the Comparison Was Built
Camp Pendleton sits in the federal Southern District of California. The federal side counts every obstruction sentence under §2J1.2 in that district, wherever the conduct happened. It does not isolate cases from the base, and nothing in the records suggests the base's cases would have gone to that court.
For the court-martial side, the records list the trial location as "Camp Pendleton", "Camp Pendleton, California", "Marine Corps Base Camp Pendleton", or "Marine Corps Base Camp Pendleton, California". The 27 convictions, all Marine Corps cases under Article 131b, had trial dates from 2017 to 2025.
The federal sentences fall in fiscal years 2016 to 2024. A federal fiscal year starts October 1 and ends September 30. Court-martial counts are grouped by trial date instead.
| Courts-martial at Camp Pendleton | Federal court, Southern District of California | |
|---|---|---|
| Convictions or people sentenced | 27 | 18 |
| Sentenced to confinement or prison | 89% | 67% |
| Median confinement or prison | 14 months | 18 months |
| A quarter received this or more | 26.5 months | 24.8 months |
| Pleaded guilty | 21 of 25 with a plea recorded (84%) | 94% |
| Mandatory minimum applied | See the caveats | 0 of 18 with the information (0%) |
Later Camp Pendleton Trials Had a Higher Median
Trials in 2016 to 2019 had a median confinement of 8 months, from 7 cases with confinement. Trials in 2020 to 2025 had a median of 16 months, from 17 cases. The earlier group is small.
The all-courts-martial median for this offense was 10 months across 329 convictions. Camp Pendleton's overall median of 14 months was higher than that figure. The records do not explain the difference between periods or between locations.
Guilty Pleas and Sentence Length
Of 25 Camp Pendleton convictions with a plea recorded, 21 (84%) were guilty pleas. Their median confinement was 14 months, from 19 cases with confinement. Contested cases that ended in conviction had a median of 6 months, but that figure rests on just 3 cases with confinement.
In the district, 17 of 18 people (94%) pleaded guilty, and 1 was convicted after a trial. Every guilty plea had a written plea agreement. The median prison term after a guilty plea was 18 months. The single trial conviction carried a 12-month term, so it cannot be read as a pattern.
Discharges and Trial Level
A punitive discharge went to 24 of the 27 enlisted Marines convicted (89%). That total was 10 dishonorable discharges and 14 bad-conduct discharges. A general court-martial heard 13 of the 27 cases (48%), and the rest were heard at other court-martial levels.
Federal Guideline Range and Other Penalties
Each federal case has a guideline range calculated under the sentencing guidelines. Of the 18 district sentences, 6 (33%) were within the range. Another 5 (28%) were below it at the government's request, and 5 (28%) were below it without one. Only 2 (11%) were above the range.
Supervised release after prison was ordered for 11 people (61%), with a median term of 36 months. Fines went to 6 people (33%) and restitution to 5 (28%). No mandatory minimum applied.
Among the 18 people sentenced, 67% were in the lowest criminal history category, category I, and 11% were in category VI, the highest. Courts-martial keep no comparable criminal history record.
Limits of This Comparison
With 27 military convictions and 18 federal sentences, small changes would move these figures. The records hold no details on what each person did or why a sentence was set where it was. Across all federal districts, 1,256 people were sentenced under §2J1.2 with a median prison term of 18 months, the same median as this district.
How We Counted
Courts-martial with trial dates in 2016 to 2025 whose recorded trial location is Camp Pendleton, California, ending in a conviction for obstruction of justice (Article 131b) (27). Federal: people sentenced in fiscal years 2016 to 2025 in the Southern District of California (U.S. Sentencing Commission district label "California South") under guideline §2J1.2 (obstruction of justice) (18). The installation is matched to the federal district for the county where it sits.
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.
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.
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.
