i know a glitch to get cold blooded pro in one game. step one: have cold blooded on. step two:light machine gun secondary ATT-S WHEN u shoot the AH OR PAVELOW OR CG. SHOOT IT WITH UR LMG

Yes it does

itt works with any plane that does not blow up but spins alot with smoke coming out of it.
Im not sure if the glitch still works or not but it is a good way to get CBP

I did it with rpd and attack helicoptor

This is how I got the cold-blooded emblem with my friend.

We would be in 3rd person cage match

One person would have a cold blooded class with a LMG (i used the RPD) He would have EMP on as one of his killstreaks.

The other person would just a class with a tactical insertion. He would have Chopper Gunner/Pavelow set as one of his killstreaks.

You let them get an EMP, then let the other person get his chopper gunner/pavelow.
You then let him call in the chopper gunner/pave low, wait till it flies to the middle of the map then EMP it.

It should start smoking and spinning out of the map. Each bullet that hits it while the chopper is spinning away counts as 1 coldblooded killstreak destroyed. I'd get about 80-90 bullets into it a game. So it only took about 6 games. (Because we would switch off)
