Yeh this is really helpful i got cold blooded emblum and title 8)

Heard this works with a that ''machine gunner'' on the AC130 shooting helicopters?

if i helped, your welcome.. and for all you guys freaking out because of a repost, as you can see with some of the comments some people didnt know about it.... =) just a refresh of the memory for those who already knew and forgot too. haha

Wish i knew about this sooner .__. had to get those 40 kills legit D:

I use a Pavelow and take it down with an EMP. so i take it down and my partner shoots it. So we don't waste ammo.

Yeah, you can shoot it down with anything except a stinger or javelin. It still smokes and spins for a while. I did mine in regular MTDM because you see them all the time.

Here is a much easier way to do it. Instead make it an Attack Helicopter. Have an LMG (the higher rate of fire the better) and the AT4-HS. Shoot it once with the AT4 then get your friend to kill you. Fire another one into it then quickly swap to your LMG and shoot at it because it will be going down. And as was previously posted each bullet that goes into it counts towards destroying a killstreak reward for Cold Blooded Pro. The reason a higher rate of fire is better for the LMG is because you will be able to get more bullets into it.

you can do this for chopper gunner, pave low, and the attack copper

lol i dont even care i just get it when i get it but nice
