KIllstreak

Killstreaks: If you are lucky enough to get 3 or more kills in a row, you are rewarded with a killstreak. These can be anything from Explosive Rc Cars, to Air Strikes, to calling in packs of rabid attack dogs. The more kills the better the killstreak. Heres a list of them, and what to use and not to use!

RCXD: (3 kills) An explosive Rc car! Almost certain to get you an extra kill. Con: You are unarmed and an easy target when using it, since you are driving the car, not defending yourself, so an easy kill. Is it really worth it? If you have a chopper gunner, fine but not 3 kills. (3/10)
Spy Plane: (3 kills) This tells you where non ghost enemy are! Instant summoning, and you know where most of the enemys are! One of the best killstreaks in CoD. (8/10)
SAM Turret: (4 kills) Utter trash...... Worst killstreak in the game. A  easy to spot,air summoned turret that steals spy plane kills. (1/10)
Counter Spy Plane(4 Kills) Denies enemies all radar support! (5/10)
Naplam Strike: (5 kills) Summon an airstrike that covers an area in flaming napalm! Great for defending objectives! (6/10)
Care Package: (5 kills) Almost as bad as the SAM. Call in a andom killstreak or ammo drop,(Mostly ammo) and have an unguarded back as you open it. (4/10)
Sentry gun: (6 kills) A minigun turret that is airdropped and shoots all non ghost pro enemys! (6/10)
Mortar Strike: (6 kills) Call in mortarts to bombard 3 different areas. (4/10)
CPU Chopper: (7 kills) A CPU heli that hovers around shooting all non Ghost Pro enemys. Great beggininng killstreak! (7/10)
Valkaryre Rockets: (7 kills) 2 controllable airdropped rockets. (5/10)
BlackBird:(8 kills) The Blackbird, or SR71 is essentailly a upgraded spyplane. It constantly tracks enemys and gives you an exact location of where they are, how high they are, what direction their facing and so on. There are no counters, so it shows Ghosts and Ghost Pro. The only way to confuse one is decoy grenades and jamming. (9/10)
Carpet Bombing:(8 kills) Call in a heavy B-52 bombardment of an area. It is immpossible to hide from, it even goes through buildings. A small area of utter shreadance. (7/10)
Chopper Gunner:(9 kills) Mount the mingun turret of a Huey, and rain destruction from above. Miniguns, need i say more? (9/10)
Attack Dogs:(11 kills) The whole piont of black ops is to get Zem Poopies! Once the dogs are called in, Nein be survivors. Eat All  Find all, shread all! (9/20)
Hind(11 kills) Just a huey with rockets. Good, but dogs are better. ( 8/10)


Good Setups with killstreaks are: Huey and Dogs, since the dogs kill the enemys on the ground, so they dont have time to attack the huey as it finishes off any survivors. Spyplane/ Black Bird, with Napalm/ Rolling thunder: This allows you to have a acurate air strike, hitting the maximum number of enemys.  Black Bird, Huey, Because they Huey is only one kill away from Blackbird, use the blackbird to hunt down an enemy and get an easy kill for the Huey!
