In brief: Army court-martial members fully acquitted 186 of 421 contested cases they decided, with trial dates from 2016 to 2025 (44%). Federal juries acquitted in 1,838 of 14,615 trials in fiscal years 2016 to 2025 (13%). The Army rate was higher, and it differed between enlisted members (47%) and officer members (31%).
This post uses the Federal Judicial Center's records of 753,808 federal defendants whose cases ended in fiscal years 2016 to 2025, compared with court-martial results from this site's Military Trial Results data (updated November 2, 2026). The series also draws on the U.S. Sentencing Commission's records of 659,036 people sentenced 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.
How Often Did Army Members Acquit?
In the Army, members are the court-martial equivalent of a jury. The records show 421 contested courts-martial decided by members, and 186 of them ended in a full acquittal (44%). The other cases ended in a conviction on every charge or in a partial acquittal. A court-martial is contested when the accused pleads not guilty to at least one charge.
Another 161 cases (38%) ended in a partial acquittal. In those cases, the members found the accused not guilty of at least one charge and guilty of another.
Did Enlisted and Officer Members Differ?
Enlisted members decided 351 cases and fully acquitted in 164 (47%). Officer members only decided 70 cases and fully acquitted in 22 (31%).
The enlisted panels decided many more cases than the officer panels. The officer figure therefore rests on a much smaller group, and a few cases would change it noticeably.
| Decided by | Cases | Full acquittals | Share |
|---|---|---|---|
| Enlisted members | 351 | 164 | 47% |
| Officer members | 70 | 22 | 31% |
| Military judge alone | 282 | 70 | 25% |
| Federal jury | 14,615 | 1,838 | 13% |
| Federal judge (bench trial) | 2,234 | 696 | 31% |
What Did Federal Juries Do?
The Federal Judicial Center counted 14,615 jury trials among defendants whose cases ended in fiscal years 2016 to 2025. Juries acquitted in 1,838 of them (13%).
Federal data does not report partial acquittals separately. Every jury trial in the federal count was a contested case, because a defendant who pleads guilty does not have a trial. The federal 13% is therefore a count of acquittals, and the Army 44% is a count of full acquittals only.
How Do Panels Reach a Verdict in Each System?
A federal jury verdict must be unanimous. In a non-capital court-martial, three-fourths of the members can convict. A conviction is therefore possible in a court-martial with votes against it, and that rule is part of how the systems differ.
Since December 23, 2024, court-martial members are selected at random to the maximum extent practicable. The records cannot show whether this change affected acquittal rates, and it may be too early to tell.
Judges in Both Systems
Army judge-alone contested cases numbered 282, with 70 full acquittals (25%). Federal bench trials numbered 2,234, with 696 acquittals (31%).
In the Army, the members rate (44%) was higher than the judge-alone rate (25%). In federal court, the judge rate (31%) was higher than the jury rate (13%). The systems therefore differ in direction, and the records cannot show why.
What the Records Cannot Show
The records do not show what evidence members or juries heard, which offenses were charged, or how any panel voted. The Army cases cover offenses under the UCMJ, and the federal cases cover all federal offenses that went to trial.
Federal cases are grouped by the fiscal year in which they ended, and court-martial cases by trial date. The comparison reports how often each kind of panel acquitted and does not show that one kind of panel is more careful than the other.
How We Counted
Army: contested courts-martial with a verdict and a trial date in 2016 to 2025, by who decided guilt. Federal: trials among defendants whose cases ended in fiscal years 2016 to 2025 (Federal Judicial Center).
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.
How "plea" and "trial" are counted. In the federal sentencing numbers, "trial" means the person was convicted after a trial, including people who pleaded guilty to some counts and went to trial on others. People acquitted at trial are not in these numbers at all (see "Who is in each set of numbers"). In the federal case data, the trial rate counts both convictions and acquittals at trial among all defendants whose cases ended, including dismissed cases. Military numbers count contested cases that reached a verdict. These denominators are not the same, and each post states the one it uses.
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.
