So, I'm almost done playing Resident Evil 4, which saddens me to say. However, with that occurring, I will most likely be spending the majority of my free time (i.e. - the little time away from work and from girlfriend) online again.
Ah, so that's where you've been. lol, welcome back.

As far as your fanfic, going with a wartime story is an awesome idea. I'd advise you to keep the ninja feel to it though, but I know you probably would anyway. Do include older ninja (I like your Kotetsu and Izumo idea), but I'd only use a few of the Rookie Nine (but that's just me - I'm sick of them due to the fillers). Perhaps you could focus on a certain squad and its mission.
