The smart-alek in me wants to say that when I think of "artillery" in a military context my mind is including the forward observers, spotters, etc as part of the concept -- observation/recon is part of "artillery", too, in the offensive sense (in that it's significantly more effective when you can aim it accurately).
There's probably a whole pointless semantic discussion on where "recon/counter-recon" fits into the modern military metaphor.
But I do take your point. :D
(also, you're only the second person named "Graydon" I've ever interacted with, and I have to keep reminding myself that you're not a voice actor I went to college with)
@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.
(Definitely not a voice actor. Nothing to do with the Rust language, either.)
