The UCMJ establishes three types of courts-martial, each with different jurisdiction and punishment authority:
General Court-Martial
The military's highest trial court, reserved for the most serious offenses — equivalent to felonies in the civilian system. A General Court-Martial consists of a military judge and at least five panel members, or a military judge alone at the accused's request. It has authority to impose any punishment authorized by the UCMJ including confinement for life, dishonorable discharge, and in capital cases, death.
Special Court-Martial
An intermediate court with jurisdiction over non-capital offenses. The maximum punishment at a Special Court-Martial is one year of confinement and a Bad Conduct Discharge. Despite being considered a lesser forum, a Bad Conduct Discharge is a federal conviction with lifelong consequences for employment, benefits, and reputation.
Summary Court-Martial
Designed for minor offenses involving enlisted members only. A single commissioned officer presides. Maximum punishment is 30 days confinement. An accused has the right to refuse trial by Summary Court-Martial, in which case the case may be referred to a Special or General Court-Martial.
