I've been playing in an organized BF3 battle series for a few months now. I've mentioned it a few times but haven't tried to promote it here, because, well, I'm lazy as hell. Anyway.
The last campaign ended, and the new one is about to begin. If you want to join in, you can sign up for their draft and get placed into one of the two armies. I played with both generals last campaign and they're both pretty nice guys.
Here's some general information organized into a wiki. It can be a bit dense to get through initially, but the basics are thus:
1) The basic structure of the game is Risk like. There is a global map with territories either neutral or held by each army.
2) Each Saturday, one army has initiative and can make attacks. They can continue attacking as long as they win. The defending army gets to choose their side on the designated map as a defender's advantage. Rounds on a map are best 2 out of 3, unless one side uses reinforcements (there's a lot of extra detail here I'm leaving out for simplicity).
3) The goal is to get your army's territory up to 75% of the entire world map and hold it through the next weekend (the next attack by the other army).
Each of these Saturdays is called a "battleday" (you'll see this mentioned everywhere). They go from roughly 1pm EST to 6-7pm EST. You do not have to play the whole day, and it's important to note that GC is pretty heavily international, with probably an even balance between US and EU players.
Last campaign, there were enough people initially to fill two whole servers. Eventually that got whittled down to enough for one server (32v32 of course). Each army is responsible for organizing itself in game and in TS. It's pretty involved and the only thing I can really compare it to is a decently sized paintball scenario.
It's a BLAST once you get acclimated. Teams tend to be very well organized and this results in a lot of teamplay that you just don't see pubbing.
