Good news today for you serious Call of Duty fans. At long last, Activision has flipped the switch on Clan Operations, a Call of Duty Elite feature that allows Elite clans to compete in events to earn clan XP, badges and prizes in Modern Warfare 3's multiplayer mode. In addition, clans can earn things like double XP and Prestige tokens as they level up.
There are two Clan Ops only for now, Sticky Fingers and Flagged for Removal. The former will measure clans by highest total captures in Domination and the latter will measure them by highest total defends in Domination. Both Ops don't start until the weekend, so you still have time to enlist your clan.
