If I could make a suggestion for using the jammer, on objective-based game modes such as Domination, Capture The Flag, Demolition, and Search & Destroy, it's probably a good idea to slap one down near the objectives- discretely, of course

Alternatively they'd be pretty good for providing you cover when you use certain killstreaks like the RC-XD, Napalm Strike, Mortars, etc that leave you otherwise defenseless.
Hmm, then again, if you have Ghost Pro, there's no reason for using a jammer to hide yourself. If anything, you'd make yourself more conspicuous because an enemy entering the jamming zone would know that you're probably close by. I guess in your situation it's really more of a team asset.
