Trickery! Deception! Not exactly the Imperial way, but certainly effective when they work. This time out you're defending a resupply drop for the Rage. The TIE Advanced is almost always going to be the right choice here, because you're going to need all the speed you can get to put yourself between the vulnerable transports and the Rebel X-Wings and B-Wings that are firing torpedoes.
The good news is that the first two waves of enemies will explode after you get their hulls to around fifty percent, a result of the sabotaged warheads they're carrying. The bad news is that you still need to intercept a bunch of proton torpedoes, then make sure that fighters making gun runs don't destroy the transports either.
