50% of Convictions Carried More Than One Year
Of 22 convictions, 19 included confinement. The median confinement was 1.5 years. Across the Navy and Marine Corps in 2021, the median was 7 months. A quarter of the sentences with confinement were 2.5 years or longer.
In total, 11 of the 22 convictions carried more than one year of confinement (50%), compared with 26% across the service. Only a general court-martial can adjudge more than one year of confinement. A special court-martial is capped at one year.
Sentences by Length
Sentences of more than 1 year and under 5 years made up 41% of convictions, compared with 21% service-wide. Sentences of 5 years or more made up 9%, compared with 5%.
Shorter terms were less common than across the service. Sentences under 6 months made up 18% of convictions, compared with 33%. Sentences from 6 months to 1 year also made up 18%, compared with 26%. Convictions with no confinement made up 14%, about the same as the 15% service-wide.
All of these figures are adjudged sentences. They cover every charge in the case and come before any plea-agreement cap, clemency, or appeal.

Full acquittals came in 20% of the 10 contested cases that reached a verdict, lower than the 26% across the service. Another 2 were partial acquittals, with a finding of not guilty on at least one charge and guilty on another.
