The qualifiers you raise are largely irrelevant. You only have a military because you want to be ready for war. In a war, no matter the reasons or participants, you're going to fire a lot of ammo. Probably more than you really wish. And you might hope you fire less of some particular sort, because of some other battlefield victory you plan on attaining, but you're still a fool if you absolutely depend on it, because the enemy gets a vote.

And all I'm saying is, plan to be able to start the dang factories again.
