What will you get in response? You will get on call fire timed in seconds not hours, exactly where you want it, powerful enough to neutralize any target you care to name. Then the light guys up front will have some real combat ability - as forward observors, not as a terror to snakes. They won't have to wait hours for it to come in, and it'll have infinite "loiter time". It will kill stuff as fast as you can see it and phone home, and as fast as completely unsexy trucks can haul the ammo up to the guns.
Why are we in this mess? It is clear the present revolution in military affairs is all about smart weapon firepower. Firepower has increased in importance drastically. And range. Instead of doctrine running with this, outside the airforce it is all razzle dazzle maneuver warfare theory instead. That is the real hidebound idea - it is so 1940.
A big part of the reason why is that the important arms for it are the least sexy in the force. Why are they unsexy? Because sexy is synonymous with needs lots of courage, and it doesn't take a lot of courage to feed a gun or truck it ammo. It works just fine. But because it works so well it doesn't really even involve serious risk to life and limb, military culture turns up its nose at it. It is geeky. No snakes are eaten. At least in the air force, the officers go off to fight in risky ways. Arty is a bureaucracy by comparison. Move guns into position, set up guns, process fire support requests, feed guns, enemy evaporates. Not sexy. Just extremely effective death-dealing.
The Army is completely dependent on the Navy and Air Force (including the Civil Reserve Air Fleet) to project its forces into the fray.
