Joe,
I would full heartily agree with you. I think the artillery should have limber units instead of supply wagons. This way you have to keep your artillery supply lines in order like the supply wagons.

This brings up another point from one of my prior post. I captured some rebel artillery that had no ammo. I had no artillery or supply wagons in sight but "voilĂ !" as soon as I captured it it was supplied and I was able to turn the guns and fire on the Rebs. That shouldn't happen if the arty had to be supplied with a Limber/Caisson.
On that note I still think that each unit should have a supply level value in the OOB file. A unit shouldn't have unlimited supply nor should it go low ammo on it's first shot based on a random number. Each unit should have a set number of ammo and it depletes it as it shoots. It would be replenished based on its size to refill the ammo supply (value).
That would be my proposals.
