Oh, I understand now, ULTRA in concept, right? Like Armistead says, could be a little difficult. Stock is definitely out of the question. I suppose it would stand to reason that RSRDC might be the most consistent and therefore a prerequisite. I'm pretty good with my Pacific history, though Armistaed seems to beat me to the punch quite often. He knows most of the major battles inside and out. Me? Well, it all depends on how tightly my head is screwed on at any given moment.

Anyway, is it even worth it to try? Something like this sounds like it needs a sticky right from the start or the thread could get lost in short order. Would need interest from other members to keep something like this alive, I would think.
Maybe the best thing to do is just keep on top of all the battle maps I've DLed from the internet. Might just be easier that way, using references on the web.
