1. Spy Plane (3 Kills): No need to explain this one, this featured in World at War and its basically the same as a UAV recon plane.

2. RC Car (3 Kills): A new addition to Black Ops. Players control a small buggy on screen, giving you the chance to drive it into enemies and detonate when desired.

3. Counter Spy Plane (4 Kills): Counter UAV.

4. Sam Turret (4 Kills): This was revealed by Treyarch recently and allows players to use the Sam Turret to take out enemy aircraft. Could come in very handy indeed were guessing.

5. Care Package (5 Kills): Could contain some if not all killstreaks in this list. It has also been confirmed that care packages will contain special beefed-up weapons to use for a short period of time.

6. Napalm Strike (5 Kills): We havent heard too much on this, but it is thought to be similar to the standard airstrike on MW2.

7. Sentry Gun (6 Kills): The trusty old sentry gun. Will never let you down unless it gets knifed in the back of course.

8. Mortar Team (6 Kills): This will probably end up being a precision airstrike, but unconfirmed at the moment.

9. Attack Helicopter (7 Kills): Your bog standard support chopper.

10. Valkyrie Rockets (7 Kills): Another new addition to Black Ops. The Valkyrie Rockets will launch a collection of rockets, to which players get to control when each rocket detonates. Sounds fun this one.

11. Blackbird (8 Kills): This is related to the SR-71 plane and will probably be a stealth-bomber type of killstreak. Lots of bodies after this one.

12. Rolling Thunder (8 Kills): Taken from Operation Rolling Thunder, this is likely to be the most damaging airstrike in the game, dealing out some serious damage in the process. Hopefully it will have steath features too.

13. Chopper Gunner (9 Kills): Could be a Pavelow, or could be exactly the same as the chopper gunner from MW2.

14. Attack Dogs (11 Kills): A hit from World at War, it will be interesting to see how the attack dogs mix up gameplay. Perfect for dealing with campers anyway.

15. Gunship (11 Kills): No specific details from Treyarch on this yet, but we know it will be a ship that players will be able to control. Must be pretty badass if its the last killstreak on the list.
