Admiral Harkov belonged to McCrae's forces and he lied to General Lindres about your new assignment. It was Lindres who provided you with a fighter.
Different time (long time ago), different galaxy (far, far away to be exact) and different game.
The Harkov example was just my response in TrashMan's comment of all conspiracy campaigns suffering from stupidity of conspirators, and someone demanding an explanation thereof...
Admiral Harkov from legendary game, Tie Fighter, is excellent example of this. Instead of just slitting the players throat, he plotted an ingenious scheme which consisted of giving the player a space fighter and putting him into an asteroid field to clear it out... then he expected his line pilots to be able to finish a pilot who had supposedly hundreds of kills, was the elite of the elite, belonged to "Emperor's Inner Circle", etc. etc.
I actually don't think Harkov made a cameo in this campaign...
