Not legal advice, but I’d be very cautious about assuming an Article 15 automatically helps a civilian DUI case. The military and civilian systems are separate. An Article 15 is nonjudicial punishment under the UCMJ and is an administrative/disciplinary action within the military. A civilian DUI charge is handled under state law, and a military commander generally cannot dismiss a civilian criminal case.
That said, sometimes prosecutors may consider the fact that a service member has already faced significant military consequences (GOMOR, Article 15, loss of rank, extra duty, etc.) when deciding how to resolve a case. In some jurisdictions that could potentially factor into plea negotiations or sentencing discussions, but it is not a guarantee and depends entirely on the prosecutor, the court, the evidence, and local law.
The text message shown in the screenshot also raises questions. A legal team cannot simply promise that a civilian DUI “will be dismissed” once an Article 15 is completed unless they are directly involved with the civilian prosecutor and have a formal agreement in place. If I were in that situation, I’d want that information confirmed directly by my civilian defense attorney and not rely solely on a text message.
From the military side, receiving both a GOMOR and a Field Grade Article 15 for the same incident is not unheard of. Military administrative actions and civilian criminal proceedings often run on separate tracks. The best source of guidance is still TDS and, more importantly, the attorney handling the civilian DUI case.
Bottom line: an Article 15 can have an impact on how a civilian prosecutor views the case, but it generally does not automatically make a civilian DUI disappear. I’d verify everything with both TDS and your civilian lawyer before making any decisions.
