the best way to get ac130 i by doing predator missile then harrier strike then ac130
primary: tar(i found extended mags to help the best)
secondary:m9(it may be weak but with fmj makes it unstoppable)
special: smoke(good when you want to get away fast)
equipment: c4 worked the best for me great on afgan to use on snipers
perk 1: scavenger pro the tar has low ammo
perk 2: danger close pro it may seem dumb but you need that for the harrier
perk 3: commando pro for close encounters
deathstreak: final stand
