FWWC & Alt Fire/Assault Resolution ORs

[Green]

I guess it works both ways? You point out that scaling fire effect by size increases impact for densely packed hexes, so that a hex stacked deep can expect to take heavier casualties than would be the case under standard PzC rules.  But it looks like the opposite is also true: a hex occupied by a single small unit can expect fewer casualties than under PzC standard rules?

I think there is a good chance that FWWC and PzC are not identical in terms of the Alt Fire rules and I can only comment on PzC.

In PzC the point at which the Alt and non-Alt fire rules produce equivalent firepower is at one-sixth of maximum stacking. Firepower is scaled up for stacking above this and scaled down below this. The scaling is linear. So firepower approaches zero as stacking approaches zero and it is multiplied by six at maximum stacking.

Something different may apply in FWWC but it may be that the concept is similar.
