Medal

In the multiplayer mode of Call of Duty: Black Ops II, medals are rewarded for outstanding accomplishments. These accomplishments can range from securing flags and bombs in objective game modes to getting an exceptional amount of kills in a single life. Each medal, including duplicates, provide bonus XP, which is displayed in the After Action Report at the end of the match.

Killstreak Medals
Killstreak Medals are rewarded for going on a killstreak (multiple kills in a single life). Scorestreaks do not contribute to this streak; only kills from weapons, the knife, lethals and tacticals are counted. Medals scale until the 31st kill, at which point each non-scorestreak kill will be rewarded with the Unstoppable medal.

Rapid Kill Medals
Rapid Kill Medals are awarded for killing multiple enemies in a certain timeframe. Unlike previous games, the timeframe to achieve these kills is much larger, and each kill extends the time to achieve the next.

Scorestreak Medals
Scorestreak Medals are rewarded for getting direct kills on enemy players from scorestreaks. Due to this, it is impossible to get medals from support scorestreaks such as the UAV. Medals stack, meaning that multiple medals can be awarded from a single scorestreak. Example: a double kill from a Hunter Killer will award two Bullseye medals.

Objective Medals
Objective Medals are rewarded for active objective play, such as capturing flags in Domination or defusing bombs. They offer some of the highest XP rewards in the game, incentivising objective play when applicable.
