@archangelzeriel @cstross Artillery _as an arm_ absolutely includes all that "what to shoot?" stuff.
Reconnaissance _as a function_ is bigger, it's maintaining the awareness of the commanders so there's some possibility of a productive decision. There's a reason Sun Tzu goes on and on about knowing yourself and knowing the enemy and has unkind things to say about generals who won't pay for spies.

Honestly, my actual problem is that I'm so ensconced in a particular mindset from being both an amateur military historian and an avid wargame player, but who doesn't talk about those things often in spaces not also 100% colonized by war nerds, that "recon" has moved from "one of the tentpoles of successful military operations" to "so self-evidently important that one forgets about it as a separate concept because not having it means you lose, full stop." in my brain meats.
