In its current state this battle is a humorous wreck. Unless you carefully read the officer briefings you will be lost on some missions. The animated briefing for #2 was a nice touch to fit the plot, but in the other missions the animated briefing should have given a clearer understanding of the mission goals. The battle has several bugs (see report) that wreck the overall feel of the game. I would advise anyone to avoid this battle until it has been repaired. Fighter orders on capital ships can ruin your day or make a mission ridiculously easy depending on what the caps lock on to.
TIE Bombers are not dogfighters, their laser placement is meant for finishing off large bombing targets. This mission would have been better in the TIE Fighter for just that reason.
It's easily winnable, but if you're sticking around for a high score prepare to dodge a bunch of missiles from the R-41s. The mission is very well made despite its flaws. It features lengthy briefing and debriefings, a fair amount of comm chatter, a lot going on for bonus goals, and even a few ships toss in just to make the scenario a bit more lively and believable.
A real difficult mission to not fail, surviving should not be hard for any skilled pilot. Go all out on the FRG and you'll make it. Not long after the mission complete, the ISD fell. After that, it's a breeze to kill everything else... with the occasional missile evasion.
