I just had a new thought that I think I will share. It originates from the time I recently spent watching band of brothers. If you want to add a little change to your cbs, without needing to think of a good way yourself, try this:
Gather up a 6v6 (or other evenly numbered) cb. Obviously, get agreement to play this way from the opposing team. Similarly to a multi-cb (described in your rules, item 17), set up the game with 4 teams. Split your 6 players into two teams, and have your opponent do the same. Now your team is not all wearing the same uniforms, and spawns in two different places! You even show up as enemies on your maps. To make this work, you really need to concentrate on your voicechat communication!
If you think this is a stupid idea, it isn't for you. In fact, no one may ever use this idea. Big deal. I just think it would add a new, somewhat chaotic element usually not present in Ghost Recon. Something perhaps more akin to... actual combat. What a novel concept. With two teams and two spawns on your side, you may very well be surrounded or exchange friendly fire, just like real paratroopers who miss their landing zone.
Think about it!
