Military tribunals in the United States are military courts designed to judicially try members of enemy forces during wartime, operating outside the scope of conventional criminal and civil proceedings. The judges are military officers and fulfill the role of jurors. Military tribunals are distinct from courts-martial.
A military tribunal is an inquisitorial system based on charges brought by military authorities, prosecuted by a military authority, judged by military officers, and sentenced by military officers against a member of an enemy army.
The United States has made use of military tribunals or commissions, rather than rely on a court-martial, within the military justice system, during times of declared war or rebellion.
Most recently, as discussed below, the administration of George W. Bush sought to use military tribunals to try "unlawful enemy combatants", mostly individuals captured abroad and held at a prison camp at a military base at Guantánamo Bay, Cuba.
