Dishonorable Discharge

This is the most punitive of all military discharges and is given as the result of a court-martial. Desertion, murder, fraud, and other crimes performed in uniform can result in court-martial proceedings that lead to a dishonorable discharge. No military benefits or future military service is possible with a military discharge characterized as Dishonorable. Contrary to popular belief there are not only the two most well-known discharges characterized as Honorable and Dishonorable; there are many more. See here.
