So, starting with the spy plane, basically the same concept from COD4, 5 and 6. When you activate this it shows the red dots on your mini-map of enemy positions.

RC-XD, this is a remote controlled car which has some sort of explosives attached to it, maybe C4? But this can be driven for as long as wanted until blown up or shot, i can't imagine the races with this in private match

Counter spy plane, basically in a nut shell this counters an enemy spy plane and makes the mini-map of the enemy scrambled.

SAM Turret, now this is a very handy killstreak when your enemies have a lot of airsupport, the SAM Turret shoots all enemy airsupport down to put it lightly.

Napalm Strike, this is like an airstrike from COD 4 OR COD 6 basically a few planes dropping bombs from it.

Sentry Gun, this is the same as MW2, just place it anywhere on the map and it will shoot an enemy that is passing.

Mortar Team, these are multiple mortar strikes which you can place on 3 parts of the map at the same time.

Attack Helicopter, this is pretty much the same as COD4 AND COD6 but now you can direct where you want the helicopter to go which is pretty cool

Valkyrie Rockets, now this is something i love, valkyrie rockets are rockets that are shot from a launcher and then controlled by the user, we get 2 of these.

Blackbird, it is essentially an overpowered UAV, this not only shows where the enemies are but also which way they are looking at.

Rolling Thunder, this is like a stealth bomber, it basically covers the entire area of the map.

Chopper Gunner, this is a helicopter which has a mini-gun and missiles which are going to be awesome but hopefully not as overpowered :/

Attack Dogs, these are the same thing from COD: WAW, they might have made them less annoying and improved them, but right now we are un-sure.

Gunship, i haven't really seen any gameplay of this yet, but it might resemble to MW2's AC130.
