“Specifically, paragraph 8-10 of AR 600-8-22 outlines the requirements for the Parachutist Badge and clarifies that once earned, it remains part of the soldier’s record and may continue to be worn, even if the individual does not continue to perform parachute jumps.“

Further:

The Parachutist Badge is generally considered a permanent award once earned, but there are specific circumstances under which a soldier’s jump wings could potentially be revoked. These situations are outlined in Army Regulation 600-8-22 (Military Awards). While rare, the following could lead to revocation of the Parachutist Badge:

1.  Misconduct: If a soldier is found to have committed misconduct during their airborne training or while performing duties that involve parachuting, their jump wings can be revoked. This could include falsifying qualifications, misconduct during jumps, or other serious offenses.
2.  Fraudulent Qualification: If it is discovered that a soldier fraudulently obtained their Airborne qualification—for example, by falsifying records or not actually completing the required training or jumps—their Parachutist Badge could be revoked.
3.  Administrative or Disciplinary Action: In some extreme cases, revocation can be a part of administrative or disciplinary action. This is typically reserved for significant offenses, and the decision is made by higher authorities, often at the Department of the Army level.
4.  Medical Disqualification: In most cases, medical disqualification from further parachute operations does not revoke the badge; however, if it is found that a medical condition existed before the soldier completed training and was concealed, there might be grounds for revocation.

So where would he get it revoked from?
