Thanks for the chance to help. I am an attorney with over 12 years military law
It is...that is, technically, in order to process for a 14c discharge
you see it provides
Commission of a serious offense. Commission of a serious military or civil offense, if the specific circumstances of the offense warrant separation and a punitive discharge
is, or would be, authorized for the same or a closely related offense under the MCM
And the maximum punishment for violation of a lawful order does include a punitive discharge.
SO they can process for an OTH
Now...I agree with you, this seems a bit silly.
But they can do it...that is they can process for a 14-12 c based on an orders violation.
The good news, for you, is that you get a hearing. And a lawyer. SO you can present evidence at the hearing that an OTH is not appropriate in your case. If you can show eiher that you did not disobey the order, OR that even if you did, it does not rate separation, I would expect the board to recommend you not be separated.
Let me know if you have more questions...happy to help if I can
