Captains are never "wrong"... but occasionally mistaken
I thought that was Warrant Officers???
So my boss in Okinawa was really a CWO-4 but had been made a Captain. When I made Captain (REAL), he reverted to CWO-4 so, as a Field Grade equivalent, he didn't have to stand CDO duty at Camp Foster any more -- I could take his place on the roster ...

Verifying those Pachencko (Japanese slot machines on base) machines every month sucked.
So as a REAL Captain, he then worked for me (sortta...not really) and I threatened to ding him on his fitness reports. He said go ahead, he would just retire that much earlier and I would have to do *everything* ...

Warrant Officers ... they get you every time.
