SAM turrets,(so much easy exp., how could I pass that up) SR71 blackbird, the third is a toss up, usually what ever there is a contract for, or just spy plane cause its so useful (though I hate getting them when blackbird is already up.)
Spy Plane, Counter Spyplane, Napalm . I picked the lowest ones because I like to rush to enemy bases and take em out quickly with my small killsteak im able to rush em over and over again. Counter is crazy cause its like somewhat narrowing their vision in the battlefield to straight ahead so flanking becomes great. and If you throw all 3 consecutive from Naplam they cant find out where in the sky the Naplam is coming from and you got an advantage over the enmy team (missing my predator missile though)
counter spy plane so rewarding to hear people get mad when i take out there blackbird and death machine since no day is complete without going rambo on someone
i've never used a death machine. everyone says good stuff about it, tho. i image its like having a huey, but one the groud
My killstreak loadout really depends on how "on-fire" I am. If I'm only doing 2.50-5.00 during a match, it's probably going to stay at UAV and SR71 with a miscellaneous one that I'm never really sold on.
When I'm doing 5.00+ and better, usually gonna be attack chopper, blackbird, dogs.
