Attempts under Article 80 were charged in 38% of the cases with charges listed, compared with 12% across the Navy and Marine Corps. 50% of convicted enlisted members received a punitive discharge, compared with 66% service-wide. Based on 18 cases · 2018 · Navy and Marine Corps records · data updated October 24, 2026 ## Attempts and Child Sexual Assault Charges 16 of the 18 records list charges. Assault under Article 128 was the most common, in 8 cases (50%), compared with 34% in all Navy and Marine Corps cases in 2018\. Article 80 (attempts) appeared in 6 cases (38%), compared with 12%. Article 120 (rape and sexual assault) and Article 120b (rape and sexual assault of a child) each appeared in 5 cases (31%). Their service-wide shares were 16% and 10%. Drug offenses under Article 112a appeared in 2 cases (12%), lower than the 26% service-wide. A case with several articles is counted under each one. | UCMJ Article | Cases | Share here | Share, the whole Navy and Marine Corps docket | | -------------------------------------------------------------------------------------------------------------------------------------------------- | ----- | ---------- | --------------------------------------------- | | [Art. 128](https://www.ucmj-defender.com/practice-areas/court-martial/article-128/?ref=bodiesburied.com) Assault | 8 | 50% | 34% | | [Art. 80](https://www.ucmj-defender.com/practice-areas/court-martial/article-80/?ref=bodiesburied.com) Attempts | 6 | 38% | 12% | | [Art. 120](https://www.ucmj-defender.com/ucmj/article-120-sexual-assault/?ref=bodiesburied.com) Rape and sexual assault | 5 | 31% | 16% | | [Art. 120b](https://www.ucmj-defender.com/practice-areas/court-martial/article-120b/?ref=bodiesburied.com) Rape and sexual assault of a child | 5 | 31% | 10% | | [Art. 134](https://www.ucmj-defender.com/practice-areas/court-martial/article-134/?ref=bodiesburied.com) General article | 3 | 19% | 15% | | [Art. 112a](https://www.ucmj-defender.com/ucmj/article-112a-drug-offenses/?ref=bodiesburied.com) Wrongful use, possession of controlled substances | 2 | 12% | 26% | | Art. 81 Conspiracy | 1 | 6% | 9% | | [Art. 107](https://www.ucmj-defender.com/practice-areas/court-martial/article-107/?ref=bodiesburied.com) False official statements | 1 | 6% | 11% | ## Discharges Were Less Common Than in the Service 8 of the 16 convicted enlisted members received a bad-conduct or dishonorable discharge (50%). Across the Navy and Marine Corps, the share was 66%. 4 of the 8 were dishonorable discharges. For enlisted members, a punitive discharge is a bad-conduct or dishonorable discharge. A sentence without one does not rule out a later administrative separation. ## Confinement 16 cases ended in a conviction, and 15 of those sentences included confinement. The median confinement was 6 months, shorter than the 7-month median across the Navy and Marine Corps. Among the sentences with confinement, a quarter were 11 months or longer. These are adjudged sentences, set at trial before any plea-agreement cap, clemency, or appeal. Each one covers every charge in the case. ## An NCO-Heavy Group of Accused By rank, the accused were 6 junior enlisted members and 12 NCOs. No officers were tried. That mix is more senior than in the Navy and Marine Corps as a whole. Special courts-martial heard 10 cases and general courts-martial heard 8\. The general share of 44% was about the same as the 45% service-wide. A special court-martial caps confinement at one year and cannot impose a dishonorable discharge. ## Pleas 12 accused pleaded guilty and 6 contested. A contested case has a not-guilty or mixed plea to at least one charge. The contested share of 33% compares with 28% across the Navy and Marine Corps. 2 of the 6 contested cases that reached a verdict ended in a full acquittal. ## Quantico and Bremerton Quantico, Virginia tried 21 cases in 2018, with a median confinement of 11 months and a punitive discharge rate of 56%. Bremerton, Washington tried 28 cases, with a median of 6 months, the same as at Yokosuka, and a rate of 46%. At Bremerton, 18% of cases were contested. | Installation | Cases | Contested | Full acquittals (decided contested) | Median confinement | Punitive discharge (enlisted) | | --------------------- | ----- | --------- | ----------------------------------- | ------------------ | ----------------------------- | | Yokosuka, Japan | 18 | 33% | 2 of 6 | 6 months | 50% | | Quantico, Virginia | 21 | 0 of 1 | — | 11 months | 56% | | Bremerton, Washington | 28 | 18% | 0 of 5 | 6 months | 46% | ## What the 2018 Records Leave Out These trials came before the Military Justice Act of 2016 took effect on January 1, 2019\. Navy and Marine Corps records before December 2020 often omit the plea and forum. Cases resolved by nonjudicial punishment, administrative separation, or no action are not included, and the records do not describe the evidence or the plea terms.
