Destroying cannon in HPS games

[FM WarB]

I've been complaining about the artillery "poof they are gone" Nappy mechanics for years. Guns just disappear after melee.
The problem with HPS ACW and Nappy games is that there is no good representation of guncrews, who with their caissons move and supply the guns.

I used to love exploding caissons in the paper games...
It would seem a computer could manage to simulate a paper stack of a gun counter, numeric counter for # of guns, guncrew counter and numeric counter for amount of ammo.
