Scorestreaks

In Black Ops 2, if you get a certain amount of points, you earn a scorestreak. There are very simple to very complex scorestreaks. The easiest and most common is the UAV, which shows you where the enemy team members are. The are also scorestreaks that can kill, such as the RC-XD and Hunter Killer. The more points you get in one life, the higher scorestreaks you can use. You can select up to three scorestreaks, out of the possible 22.

Scorestreaks

However, scorestreak kills do not count as actual kills, but you still get points from them.
