Can't think of anything to say XD
I would never apply an RC to my scorestreak but when I do get one from a care package I find it's a lot easier than on the first Black Ops. Once in a while an RC can be a funny experience
RC's can be handy if someone is camping and you want to sneak in a bomb without them noticing you
The RC-XD is different than the one from the first Black Ops.
