UAV Jammer

Just to clear things up, many consider the UAV Jammer useless because of the silencers, but they are entirely wrong. The silencer only hides you from the GPS, when an airborne UAV is sent out it doesnt matter if you have a silencer on or not, you will still show up. The only way to completely hide (even when firing your weapon) when a UAV is out, is to have the UAV jammer perk.

The perk is great for sneaking around and flanking the enemy, especially against snipers in levels such as pipeline, Crossfire, Overgrown, etc. But if sneaking around enemy lines isnt your style then this perk could probably be better spent.
