Every article of the UCMJ has that phrase in it. That is there if the convicted party wishes to appeal the punishment meted out by their commanding officer for the offense. It's a catch-all.
The punishment for an Article 92 offense, as with the vast majority of UCMJ offenses, is determined by the Commanding Officer at an Article 15 (Army) or Captain's Mast (Navy). The punishment usually results in up to a loss of rank and/or loss of pay.
If the guilty party feels they are innocent, they can then ask for a court-martial.
A court-martial does not automatically mean a prison sentence or loss of pension.
As I said, I am a retired vet. I know more than the dumbasses in this topic who think it is a crime to remind soldiers they are allowed to disobey an unlawful order.
It simply isn't a crime, any more than telling someone they dont have to vote for Trump. Though I'm sure many Trumptards wish it was.
