Hey Jeff
I'm pretty clueless when it comes to TIE, unfortunately. However, knowing where to look for mission help, I tried the old Black Knights site; sadly though, there was nothing about the mission there, either.
You could try posting a question on MECantina.com (second link in my signature) in the X-Wing forum (don't worry, that's where they discuss all of the space sims, TIE included). I know Mark "Havoc" Hofmann, the former Black Knights leader, hangs there and could probably help you with this mission.
