Exactly so you can shoot down the killstreaks since they cant see you. Help hour team out. But this is Call of Duty there's no such thing as team work.

Why would u put a stinger on if u have cold blooded. Is it a team thing? Because i only use stinger they get a UAV and i dont have cold blooded. The highest kill streak they usually get is UAV. a harrier strike is kinda rare. You cant shoot down a predator missile with a stinger so ur going to die unless you find a safe area. Write additional details

if you wanna noob it up use a silenced ump with cold blooded, like someone said UAV is usually the highest and you can shoot it down with the ump, use marathon cold blooded and ninja to sneak about and as a secondary use something that will be better for long range like a thumper or an rpg because ump is a pretty close combat gun anyway and with a thumper u can nail a long range kill fast before they can duck down while you try to burst with yoru ump at long range.

If u wanna have some fun use a p90, they rape ;)

Only if you need cold blooded pro. Don't use cold blooded every round because it makes you look like a noob if you didn't know. you should know when you need it and when you don't.

there is not reason why.i say screw my teammates.
