The forum through which criminal cases are tried in the United States armed forces is the
court-martial. This term also applies to the panel of military officers selected to serve as the finders of fact or "jury". (In other words, they fulfill the role of a civilian
jury in trying criminal cases.) The
Uniform Code of Military Justice (UCMJ) outlines three distinct types of courts-martial.
General court-martial • jurisdiction over crimes committed by any person, including civilians, covered by military law at the time the crime was committed • forum for the most serious charges such as
treason,
espionage,
homicide,
sexual assault,
drug distribution, or
desertion • officers detailed to the court are defense counsel, trial counsel (prosecutor), and military judge • a court-martial panel (or "jury") comprises five or more service members, at least one-third of whom are enlisted if requested by an enlisted accused • accused service member may request a trial by judge alone in lieu of trial by a panel of members, except where the death penalty may be adjudged • maximum sentence that a general court-martial can impose is the maximum specified in the specific UCMJ Article (crime) the accused is convicted of, including death and/or a dishonorable discharge.
Special court-martial • jurisdiction over crimes committed by any person, including civilians, covered by military law at the time the crime was committed • forum for intermediate offenses such as the battery, assault, larceny (theft), minor drug-related offenses, unauthorized absence, disrespect, disobedience, and similar offences • officers detailed to the court are defense counsel, trial counsel (prosecutor), and military judge • special court-martial panel comprises three or more members, at least one-third of whom are enlisted if requested by an enlisted accused • accused service member may request a trial by judge alone in lieu of trial by a panel of members • regardless of what crime is charged at a Special Court-Martial, the maximum sentence that can be adjudged is 6 months' confinement, forfeiture of two-thirds pay for 6 months,
reduction in rank, bad conduct discharge, and a fine • a special court-martial cannot dismiss an officer
Summary court-martial • jurisdiction over crimes committed by enlisted personnel only • forum for minor offenses such as petty theft • summary court-martial comprises a single officer whose pay grade should not be below O-3 • maximum sentence is one month's confinement, forfeiture of two-thirds pay, reduction in rank to E-1 • summary court-martial may not adjudge punishments of confinement without hard labor or reduction except the next inferior pay grade for accused who are in the pay grade of E-5 or greater • can be refused by the accused, in which case the matter is normally referred to a special court-martial == Appeals process ==
