Star Trek bridge officers
Sorry to burst your bubble but I’m 98% positive Chekhov was NOT security chief. Security wears read. He’s a helmsman and a science officer. Duh.
Now that you pointed that out, I’m really confused by what possessed the person who made this chart to think that he is security….. He’s more like Data that Worf in that respect, and, furthermore, I think he’s the helmsman/science guy and Sulu is Navigator. Or, at least, one of them is Navigator and one is Helmsman.
