FWWC and artillery ammo consumption

[Volcano Man]

Actually, its not the stockpiling, its the supply level in general that makes the most difference here. The supply levels are high in the early campaign, meaning that the artillery will almost always be available (unless the commander is not managing his chain of command properly, or putting his units in places with a low local supply). In contrast, in the late campaign, artillery will simply not be able to fire half or most of the time and this represents the decline in overall stockpiles of ammunition.

In the early campaign there is a small chance of stockpiling of ammunition, and it is really intended to be something that plays a role when front settles to static positions. I didn't want it to be such a high level that guns were stockpiled very often as this was not the case AFAICT.

The short answer is that all this has been factored in already. ;)
