Oh, I do love the pronouncements of "experts" - and I will go you one better: if you haven't been on the ground, within 300m of a fortified trenchline of the enemy as they cut the grass shorter around you with their massed small arms fire, then you don't know what the recipient's view of CAS is. For your edification, I have sent 9-lines with the best and during my stint after active duty designing advanced technology systems, I helped design ACASS.
Getting the "bombs on time" requires direct communication between the fast movers and the ground pounders, with close and intimate knowledge of the ground situation, friendly locations, fire support coordination measures/restrictions, and the right effects for the target.
JDAMs are gorgeous but sometimes a well placed line of 20mm or 30mm or rockets are what the doctor ordered.
BTW, I used to be a Navy and Air Force qualified FAC, a Naval Gunfire Spotter and a Forward Observer - in combat.
No airsoft here, compadre.
Aviators at a forward deployed airfield are the recipients of force protection provided by experts in airfield protection. Do you think the aviators should dictate what equipment and tactics the force protection units employ? And as a Marine FAC, how many CAS missions did you coordinate with slow moving, fixed wing, Marine assets?
And JDAMS have almost no CAS application. LGBs...loads.
