In this campaign you play mainly with the Fang missiles. You have plentiful of them in your tiny Anubis, they are as fast as VLL and much deadlier. I ran the whole campaign (not that long though) in Medium without problem, and I think letting us nothing but the deathtrap the Anubis is, makes for a very interesting and quite challenging gameplay.
So comparing GTA and PVN armament, the Fang is must deadlier in dogfights than either the ML-16, the MX-50 or the Fury, even if it seems a bit less effective against cruisers. The missile banks of the Anubis are quite well-placed too, compared to how badly placed most primary banks are on Vasudan fighters.
