I recently purchased VOY Season One and have been enjoying it thoroughly. However, I have a question: Why does it appear than LT. Tuvok is wearing Lt. COMMANDER pips? Am I wrong? My understanding thus far is: 1 pip = Ensign (1 gold pip + 1 black pip = Lieutenant Junior Grade) 2 pips = Lieutenant 2 gold pips + 1 black pip = Lieutenant Commander 3 pips = Commander 4 pips = Captain While I love watching the series again, this detail bothers me. I used to have a link to a very good website showing all the Trek rank insignia, but have lost it over time.
