UAV helps the game stay fast-paced by keeping the players finding each other and going at it. Thing is as the developers have said they have made sure EVERYTHING has a counter. This one's counter is particularly obvious as it has "Counter" in the name. It's called "Counter-UAV" It admittedly is a little far down the road but still shouldn't take too long to unlock. Stop complaining and equip that scorestreak when you unlock it.
