Which of the following is NOT a form of administrative discharge?

The correct choice is dishonorable discharge, as it does not fall under the category of administrative discharges. Administrative discharges typically involve decisions made by the military for reasons other than the individual's misconduct or criminal behavior. They can be classifications based on the service member’s conduct and performance.

An honorable discharge is given for satisfactory performance, general discharge denotes a release from active military duty under conditions that are neither honorable nor dishonorable, and an other than honorable discharge usually indicates a pattern of behavior or minor misconduct. In contrast, a dishonorable discharge is a punitive discharge resulting from a court-martial for serious offenses, reflecting a significant breach of military discipline and conduct. Therefore, it stands apart from administrative discharges, which are not the result of punitive actions.
