It is possible. The article says the Commandant “took adverse administration action against him.” The could range from a letter of reprimand all the way to a general courts martial.
First half correct, but a court martial is a military justice (criminal) action (not administrative). An officer cannot be demoted, but can be dismissed from the service by a court martial panel. Administrative action
can be followed by retirement in the “highest grade in which the officer served honorably”. To the shame of my Corps, we had a TJAG (2-star) who was retired as a colonel and a future TJAG fast-burner type, meeting his Brigadier General board, who retired as a 2LT when it was discovered that he’d been disbarred before entering the JAG Corps.
I agree, likely a letter of reprimand with UIF entry or an Article 15. Regardless, he’s toast, career-wise.
Colonel, USAF TJAGCR (Ret)
That is extremely unlikely considering the differences in punishment options.
