10. Guard Dog
Everyone loves a dog, especially if you're camping. Man's best friend can be particularly useful, but also very annoying.
9. Sentry Gun
Sentry guns are a CoD classic. They're effective and always seem to give a greater sense of security than is probably deserved.
8. Support Squadmate
These friendlies add to your Killstreak and pick up ammo/vests for you. They are super sweet if used in a timely manner.
Knife > bullet (classic CoD). Maniac is fun as butts, though.
6. Valkyrie Rockets
This is a great anti-aircraft Killstreak. But, also, who wouldn't want to be in the POV of a missile?
5. Helo Pilot
Once you get in a helicopter, it gets easier to start picking off some of the campsites that've been taken over.
Basically a tank in the sky. This is one of the nicest aircrafts to control and can be super rough to get rid of.
3. Attack Dogs
These bad boys take on the map with one-bite kills. They get the number-two spot because you can't shoot them down from the sky and, again, because everyone loves a dog.
2. Stealth Bomber
This throwback isn't always the easiest to manage. But it's super powerful if you can direct the line of fire in the right way.
