The soldiers are the ones who actually were from this place, after all. They'll have first-hand experience with the war. I don't think we're in so good standing that we can be allowed to just rush into battle unsupervised.

[And having some guidance is better than rushing onward with no clear goal. Win a war? If only settlement was as easy as both sides duking it out in a big winner-takes-all fight like they do in shounen comics.]
