I've been looking at Miles O'Brien's career in Starfleet and I get the impression that he must have been demoted at some time in his career. I've been trying to sort it out with the help of Memory Alpha but haven't found the definite answer yet.
In the first season of TNG he's actually an ensign with one pip.
In season 2 of TNG he has two pips on his collar and is adressed by Riker as Lieutenant.
he wears the pips of Lieutenant until season 6 of TNG when he all of a sudden is wearing a single hollow pip whic obviously is the rank of a Warrant Officer!
He continues to wear that single hollow pip during the first seasons of DS9, actually joking that "if Nog graduates from Starfleet Academy, I must adress him as Sir".
In season 4 of DS9 he gets a new rank insignia, reminding of a Sergeant's insignia.
So what did poor Miles do to be demoted? Did he spike Picards Earl Grey with Irish Whiskey? Or did he reveal Riker having an affair with some married female Ensign?
And why that new rank insignia in Hippocratic Oath. Was he demoted to Sergeant by Sisko for throwing some tool at Jake when Jake failed to obey him or what? Or did he cough in the wrong tune on a Friday morning briefing:
Miles, Miles, Miles, what have you done?
