What I do is order my wingmen to guard certian ships, then I go full burners towards the Lindos. I take out the Lindos beams, but not before sending alpha 2 in first to act as a decoy. While A2 is busy getting fried by the Lindos defense systems, I stay a fair distance away and snipe the forward beams. When all the beams are down, I fly back to the fleet and defend the smaller ships on the port side of the Hecate-looking thing. During phase 2 of the mission, I make like T-Man and get really close to the Nemesis. I stop at one beam, take it out, and move on to the next. This way, no more than one or two turrets can fire on me at once. For extra protection, I call all remaining fighters to form on my wing as I complete my task. If I run out of missles, I divert full energy to guns and slowly take out the beams of the Nemesis.
