FASCAM - Gamey or not?

[Liebchen]

Unobserved fires tend to be ineffectual.

I may have missed some subtleties in this thread, but it seems to me that any area that is undergoing unobserved FASCAM fire is also unobserved by the supply train, itself. In other words, the supply train that does not see the dispersal of the mine ordnance, is also not in a position to pass through the terrain to deliver the supplies.

Keep in mind that our supply convoys are virtual. In real life they would would have to bop down the road, take occasional (or frequent) detours to avoid contact, hiding from enemy air interdiction, etc. So, the idea that any one-square-mile piece of acreage could automatically provide access for supply is, itself, a complete abstraction.
