Or you could, you know, play the RP from a narrative standpoint instead of trying to be an armchair general. Less about gunporn and army wank, and more about really dipping into what makes a nation tick. 

To be real, I've yet to see an NRPer conduct his or her military in a proper manner, the reason for this I attribute to the fact no one really knows a lick of anything about actual warfare.

Additionally, I plan to play a fantasy species that in no way adheres to the usual rules and/or formulas associated with conventional human-style warfare, so I don't see how a stats system is really going to benefit nonhuman species unless you're really going to limit people to the usual boring Tolkien-style races and whatnot.
