I was just doing the exact same thing. Of the Recruit rank, the players Relent, Ken, StandbyRanger, Tristar all seem to be active on the site, and I think Really a Clever Add-Bot is as well, but is having some issues at the moment or something?
There is a roster of Imperial Armed Forces members in the Imperium forum somewhere. I'll find it and link it here. We could attempt to PM/VM people from there and see if they're interested.
War games do sound like a lot of fun and would be a great training thread. I'd imagine the weapons used would be stun weapons and everything, considering the idea really isn't to kill each other but to complete whatever objective your squad has been assigned.
Hey, just wanted to let you know I created an interest check thread in the Imperial OOC board about possible simulation training stuff you mentioned as well as about the Valarian Gang mission pack. I know the simulation stuff was something you were interested in so I thought I'd just drop you a line about it :)

Opening posts are possibly the worst things I'm ever able to do. I more prefer establishing scene as we move through, rather than immediately in the beginning. Tis one of the many reasons its beginning is somewhat lacking, and I apologize. Regardless, our training thread is started, sorry I wasn't able to do it earlier, had work >_<
