If you want you can join my clan CombatControl, there are no requirements. I enlist in bo2 and mw3 challanges and ops. I understand if you cant play the ops/ challenges once in a while because of your social life. As long as you try to participate in some of them. I have small bandwith so right off the bat i cant particeipate in everyone. We are currently level 6 with 7 members. Here is the link to my clan,
