There are no ranked Black Ops 2 clans yet as everyone starts at Level 1. The clans section of the forum will bring you more luck I would think.
I also see there are some limited clan HQ unlocks on elite now, for those interested. #spoiler
Level 50 on MW3 but you have to apply and after that you have to prove your loyalty.
what's the clan name? and how do i prove my loyalty?
For what kind of game modes?
