Welcome to Star Trek Answers. What would you like to know?

no, he was always an NCO. Worf's father identified him as a CPO despite the LT rank pips he wore in "Family" so evidently those do not make him a full LT.

^^Wrong. O'Brien was referred to as "Lieutenant" in the TNG episode "Where Silence Has Lease."


I think it's pretty clear that at first, O'Brien was an officer, and then he wasn't. Reminds me of the M*A*S*H episode where Radar was given a field promotion to second lieutenant and then decided he didn't like it. Or maybe it was to make the point that you don't have to wash totally out of Starfleet. O'Brien certainly was a very highly-regarded transporter technician who saved a lot of butts just in the nick of time ProfessorTrek 21:57, August 4, 2011 (UTC)
