My most used are UAV - Care Package - Counter UAV.
You can rack up some serious points with that setup in no-time.
Same Here. Definitely my favourite setup.
Domination - UAV, Lightning Strike, Orbital VSAT
Anything else - UAV, Hunter Killer, Lighning Strike
Hunter Killer, Lightning strike and recently been trying the Guardian which I'm loving.
Hunter Killer Drone
A pretty good domination setup. UAV hepls your teammates, The hunter killler is good if someone is capping/defending flags, so you can clear the area and start capping/defending it yourself. And the Orbital VSAT is, I don't even have to explain it right? The only thing bad about it is that I only get it every 10 matches or so, but I always get pretty close to getting it. UAV, CUAV and Orb. VSAT is a pretty good trolling setup too
vsat/emp/K9 or swarm
the first one, well just easy to obtain, so usually roll with that when the game doesn't feel right (most of the time thus)
second, once you get that vsat/emp it's a guaranteed k9/swarm
the vsat and emp rack you up so many points once used together it's crazy
you can litterally hang back not get a single kill and get a swarm if you have a few decent guys on your team
UaV, Counter, Hellstorm or lightning strike. sweet and simple.
UAV, Care Package, Hailstorm.
