In brief: The median adjudged confinement for the 12 child pornography (images of child exploitation) convictions at Joint Base Lewis-McChord courts-martial was 13 months, for trials from 2020 to 2025. People sentenced in federal court in the Western District of Washington for possessing, receiving, or distributing this material in fiscal years 2016 to 2025 had a median prison term of 68 months. The federal count of 164 covers the entire district, not the base, and most of those defendants were civilians with no military service at issue.
This post uses the U.S. Sentencing Commission's records of 164 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.
Federal Cases Come From the Whole District
Joint Base Lewis-McChord is in the Western District of Washington. The 164 federal sentences counted here are every sentence under guideline §2G2.2 in that district over 10 fiscal years. They are not cases from the base, and this post does not suggest that any base case would have gone to federal court.
On the military side, the records list the trial location as "JB Lewis-McChord, Washington" or "Joint Base Lewis-McChord". The 12 convictions break down as 10 Army cases and 2 Air Force cases. That is a small count, so each sentence carries real weight in the median.
Confinement and Discharge at the Base
All 12 convictions with a sentence recorded included confinement. The median was 13 months. A quarter of the accused received 26.9 months or more.
Each of the 12 enlisted members convicted received a punitive discharge. The discharges were 6 dishonorable and 6 bad-conduct discharges. All 12 cases were tried at a general court-martial.
| Courts-martial at Joint Base Lewis-McChord | Federal court, Western District of Washington | |
|---|---|---|
| Convictions or people sentenced | 12 | 164 |
| Sentenced to confinement or prison | 100% | 99% |
| Median confinement or prison | 13 months | 68 months |
| A quarter received this or more | 26.9 months | 120 months |
| Pleaded guilty | 10 of 12 with a plea recorded (83%) | 98% |
| Mandatory minimum applied | See the caveats | 75 of 164 with the information (46%) |
Pleas and Contested Cases
Of the 12 convictions with a plea recorded, 10 (83%) were guilty pleas. The median confinement after a guilty plea was 12 months.
The other 2 were contested cases that ended in conviction. Their median confinement was 72 months. A count of 2 is too small to support any general statement about contested trials at the base.
Federal defendants in the district pleaded guilty more often: 160 of 164, or 98%. Only 4 were convicted after a trial. The median prison term for those 4 was 200 months, compared with 64.5 months after a guilty plea.
Mandatory Minimums and Supervision in Federal Court
Federal law sets a mandatory minimum prison term for some of these offenses. In this district, a mandatory minimum applied to 75 of the 164 people (46%). The table does not give a court-martial figure for this measure, and the caveats below explain why.
Prison was close to universal: 162 of 164 (99%) received a prison term, and 2 received probation only. A quarter received 120 months or more, and a quarter received 36 months or less.
The 162 people ordered to supervised release had a median term of 180 months. For 40 of them (24%), supervised release was set for life.
Where Federal Sentences Fell Against the Guidelines
Most sentences in the district were below the guideline range at the government's request: 58%, or 95 people. Within-range sentences made up 21% (35). Sentences below the range without a government request made up 19% (31), and above-range sentences 2% (3).
For reference, the all-district federal median was 90 months across 13,646 people. All courts-martial for this offense in the data had a median confinement of 22.5 months across 491 convictions. The base median of 13 months was lower than that court-martial figure.
What These Records Leave Out
A court-martial sentence here is the sentence adjudged at trial. It does not reflect clemency or appeals. A federal prison term is the term imposed, not the time a person served.
The military figures follow calendar years by trial date, and the federal figures follow fiscal years that start October 1. Neither set of records explains the reasons behind any sentence, and court-martial records have no criminal history field to compare with the federal data.
How We Counted
Courts-martial with trial dates in 2016 to 2025 whose recorded trial location is Joint Base Lewis-McChord, Washington, ending in a conviction for child pornography (images of child exploitation): possession, receipt, or distribution (12). Federal: people sentenced in fiscal years 2016 to 2025 in the Western District of Washington (U.S. Sentencing Commission district label "Washington West") under primary sentencing guideline §2G2.2 (possessing, receiving, or distributing child pornography; 18 U.S.C. 2252 and 2252A) (164). 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.
Mandatory minimum sentences. Many federal statutes on drugs, images of child exploitation, child sex abuse, and firearms carry mandatory minimum prison terms. The UCMJ has mandatory minimums only for a few offenses (a dishonorable discharge or dismissal for rape and sexual assault, and life for premeditated murder). Federal sentences for these offenses are partly set by Congress, not by the judge.
