COD MW2 Killstreak Perks...

i think that's how i have mine set up, sometimes i use the sentry gun though.

I like to use the UAV. I play a run & gun play style so knowing where people are is imperative. I may switch it up though, since usually other people can provide a UAV though. In fact I think I will.

In that case I'll go with
4 - Care Package
7 - Attack Helicopter (not my favorite...switching to Pave Low next time I get an unlock)
11 - AC130

Depends on the map for me.

I always use UAV. Always. I move around alot and I like to know where people are. On some maps I use the predator, like Afghan or Wasteland, where they are usually clumped together and sniping so I know where they are exactly. On some of maps with alot of buildings I use care packages and hope for Counter-UAVs. On Domination I use Sentry guns and care packages.

Right now its:

UAV
Predator
Pave-Low
