Interesting debate you are having with yourself CF.
I have not tried this because I generally don't use my valuable arty or CAS for recce. I try to use these resources as realistically as possible, to pound the bejesus out of areas I want to suppress to allow a safer passage for my troops. Then as choke points or high value targets come into view hit them with CAS and any handy arty missions. Now if the enemy unmasks an AAA unit when I launch an airstrike and I have arty coming down within a reasonable distance, well then that’s a different story. I especially loathe 40mm AAA.
Prosit!
