More like "skillstreaks".
They're rewarded for a skilful kill (headshot, melee, other stuff) and enemies drop holographic, customisable dog-tags. The player picks up this dog-tag, and their skill-kill-count increases.
You keep this count, even after you die and respawn.
Kills which skillstreak rewards make don't create dogtags. Therefore, you can't rely on the gunship to earn you 500+ kills and a giant-flying-Pinger-with-lasers-and-nukes. You need to do it the hard way.
