Included is all the sounds in the Xbox demo of the game. This should be most of the included sounds because there wasn't really that much. There's some tactical VO, shell VO, sounds, background sound clips, and other goodies. Same issues as with PS2, you're going to have to dig through the hashes (and some of them didn't name correctly anyway).
I've already done the work of converting them back to a munge-friendly format that should play on any media player.
