There is a calling card called Boot Camp Graduate, it says you have to "Earn all Boot Camp unlocks" to unlock the calling card. I've searched Google and 7S, even the CoD Wiki and I can't find anything about it, it's number 83 out of 84 under the General tab O the calling card selection screen. Anybody know what a boot camp unlock is? I have 21 out of 23 completed it says, but I've no idea what I did to get those 21 "unlocks". Thanks.
