They as good as ended his career with that. You don’t think every sailor hasn’t already heard or will hear at his next command that he is so ignorant he can’t even fire a rifle right? If he’s that incompetent they shouldn’t have let it get so far that he got a command in the first place. He’s either so incompetent that he can’t do basic sailors tasks OR they made up a reason to fire a sailor who made a non critical mistake. Do we publicize IN PRINT when an army infantry NCO has a negligent discharge at clearing barrel? Maybe locally, but it doesn’t mean he is completely unfit to lead men to war.
I was 8. Lost a tooth at my grandparents house and my grandpa chose to wait until after sunrise to take the tooth and return some tooth fairy treasures.

I kept the secret until they asked directly and just didn’t lie. They seemed to have turned out fine.
