fire value for mortars

[Green]

Thanks for your input. I'm still not seeing a rule which explains that the fire value linearly goes  to zero against hexes which are not fully stacked (edit: but I think Green is right in his last post, that the mortar fire is sort of treated the same way, although not exactly the same and not documented as far as I see. See also edit below)

I agree that this does not seem to be documented but if it works along the lines that I suggested then it appears logical. Not everything is documented and this may have been deliberately omitted to reduce the complexity of what is already an extremely detailed manual. Or perhaps it was overlooked. Either way, to me, it appears to be a feature rather than a bug.
