In brief: In the federal Western District of Oklahoma, 202 of the 368 people sentenced for simple possession under 21 U.S.C. 844 (55%) received probation only. At Tinker AFB, Oklahoma, 16 of the 17 Article 112a drug use convictions with a sentence recorded (94%) included confinement. The median confinement at Tinker AFB was 3.9 months, while the median prison term in the district was 0.7 months for those sent to prison.
This post uses the U.S. Sentencing Commission's records of 368 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.
Probation Was the Most Common Federal Sentence
Of the 368 federal defendants, 164 (45%) received a prison term. The remaining 202 (55%) received probation only, with no prison or other confinement. Among those who did go to prison, the median term was 0.7 months, and a quarter received 1.5 months or more.
Confinement was the usual result at Tinker AFB. Only 1 of the 17 convictions with a sentence recorded had no confinement. The median adjudged confinement was 3.9 months, and a quarter of the convictions carried 4.9 months or more.
So the courts-martial at the base sent people to confinement more often, and for longer terms, than the district court did for this charge. That is a description of these groups, not a measure of how the same case would be treated in each system.
| Courts-martial at Tinker AFB | Federal court, Western District of Oklahoma | |
|---|---|---|
| Convictions or people sentenced | 17 | 368 |
| Sentenced to confinement or prison | 94% | 45% |
| Median confinement or prison | 3.9 months | 0.7 months |
| A quarter received this or more | 4.9 months | 1.5 months |
| Pleaded guilty | 5 of 6 with a plea recorded (5 of 6) | more than 99% |
| Mandatory minimum applied | See the caveats | 3 of 112 with the information (3%) |
Who Is in Each Count
Tinker AFB is in the federal Western District of Oklahoma, and the installation was matched to that district through its county. The 368 federal cases are from across the district. They are not cases from the base, and most did not involve service members.
The court-martial count includes 17 Air Force convictions where the records list the trial location as "Tinker AFB, Oklahoma." Their trial dates run from 2017 to 2025, counted by trial date. The federal count covers people sentenced in fiscal years 2016 to 2025, and each fiscal year starts October 1 and ends September 30.
Article 112a covers wrongful use, and federal law has no charge written the same way. The nearest federal charge is simple possession, so the offenses being compared are related, not identical.
How the Federal Cases Were Resolved
Almost every federal defendant pleaded guilty: 367 of 368 (more than 99%). 1 person was convicted after a trial and sent to prison for 160 months. A single trial result says nothing general about trials in this district.
The median prison term after a guilty plea was 0.7 months. Among the guilty pleas, 4% had a written plea agreement and 86% were straight pleas with no agreement.
The sentence was within the guideline range for 343 of the 368 people (93%). 13 (4%) were below the range at the government's request, 11 (3%) were below it without a government request, and 1 (less than 1%) was above it. A mandatory minimum prison term applied to 3 (3%).
Pleas and Contested Cases at Tinker AFB
A plea was recorded for 6 of the Tinker AFB convictions, and 5 of those 6 were guilty pleas. The median confinement after a guilty plea was 2.6 months, across 5 cases with confinement.
The 1 contested case that ended in conviction with confinement carried 36 months. One case cannot set a median that means much, so this figure is best read as a single sentence.
5 of the 17 convictions (29%) were at a general court-martial, the court-martial level used for the most serious charges.
Discharges and Officers
Of the 15 enlisted members convicted, 10 (67%) received a punitive discharge: 1 dishonorable discharge and 9 bad-conduct discharges. 2 officers were convicted, and both were dismissed. Dismissal is the officer form of a punitive discharge.
Federal court has no sentence like a punitive discharge. On the federal side, 159 people (43%) were ordered to pay a fine, and 2 (less than 1%) were ordered to pay restitution. 19 people (5%) were ordered to serve supervised release after prison, with a median term of 12 months.
Earlier and Later Tinker AFB Trials
Tinker AFB trials from 2016 to 2019 had a median confinement of 4.9 months, based on 7 cases with confinement. Trials from 2020 to 2025 had a median of 2.6 months, based on 9 cases. The later median was lower, but both groups are small, and they do not establish a trend.
For a wider view, all courts-martial for this offense in the data had 1,071 convictions and a median confinement of 3 months. All federal districts together sentenced 6,268 people, with a median prison term of 6 months. Both Tinker AFB and the Western District of Oklahoma differ from those totals, in opposite directions.
Criminal History and Other Limits
In the district, 39% of those sentenced were in criminal history category I, the lowest, and 10% were in category VI, the highest. The court-martial records have no criminal history field, so this cannot be compared.
Court-martial sentences in this post are as adjudged at trial, before clemency or appeal, and federal terms are as imposed, not as served. The records do not show the drug, the amount, or the facts of any case.
How We Counted
Courts-martial with trial dates in 2016 to 2025 whose recorded trial location is Tinker AFB, Oklahoma, ending in a conviction for wrongful drug use (Article 112a), compared with federal simple possession, the nearest federal charge (17). Federal: people sentenced in fiscal years 2016 to 2025 in the Western District of Oklahoma (U.S. Sentencing Commission district label "Oklahoma West") under a conviction under 21 U.S.C. 844 (simple possession), the nearest federal charge (368). 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.
Drug use has no federal counterpart. Federal law does not make drug use a crime. A positive drug test is not a federal offense; a civilian can be charged only with possessing the drug. Bringing drugs onto a military installation is also a military-only offense. For these, the nearest federal charge is simple possession, and the post says that the match is not exact.
