At the start when you take control of the RSE Hawkeye and wait afew seconds for the Border Patrol to send you another communication, they refer to you as the Tribune
Also after you gain control of the Freighter after capturing it, you are referred to as Tribune again, and I think a third time when you enter the 1st system.
Well actually they refer to you as "Tribune" not "the Tribune", sorry about the confusion. I was just pointing out why Tribune is mentioned (I know it's the name of the Romulan ship in KA since I just finished it a week ago) since the ship the player controls is called Hawkeye.
