Step-by-step explanation:
The information provided does not directly answer when a nonjudicial punishment (Article 15) will be destroyed. For accurate information regarding the procedures for the destruction of nonjudicial punishment records, one must refer to the specific military service regulations which vary between branches of the United States Armed Forces. Timing for the destruction of these records typically depends on the severity of the punishment, the level at which it was administered, and the service member's rank. However, it generally ranges from two years for minor infractions to permanent retention for more severe offenses. The specifics of when Article 15 is destroyed should be sought from the applicable military legal office or in official military personnel policy documentation.
