COD4 is a rather popular game at this time and I'm certain that many people here at CP play on PC. Like the PS3 username thread I thought I would see who on CP plays and what their in game username is and where they play.
I play as.... wait for it.... Buff.

I know. Who would've thought?
I mostly stick the same few servers, depending on who and how many is playing.
I don't have server IPs at this moment, but I stick to these servers:
5307th Rangers - I've played Spearhead with these guys for a few years. When they made the jump to COD4 I did too. A few of them used to be in the same clan as me.
105th STS - I also used to play Spearhead with them, as well as COD2.
ETFU - Another bunch of guys who used to play Spearhead. The founders of this clan came from the 5307th clan.
There are a few others, but I mostly stick with those three servers. All the servers I play on are run by clans that have their origins from Spearhead, most specifically the tactical community (Tactical Realism - no running unless for cover, no jumping from unrealistic heights, no bunny hopping, etc).
So, who are you and where do you play? Maybe we know each other, or maybe we've seen each other without knowing we also belong to the CP community.
