The Supa/ fighters should be oyour only problem on this mission. Just set your turets to atuo-fire, and keep the fighters in the moeny lane.
ONe trick is to destroy all but on of a Fighter in a Fighter group... (i.e. a FG of 4 fighters, take out all but the lead one) This will allow you more time, and less fighters.
normally i get one fighter to about 50% hull, and leave him alone. SO when i target, i know the one with 50% hull is the one I am saving.
Tho someimtes your mates go after him
