I quite seriously don't see any ambiguity. There is only one wound pool. The word "any" makes clear that just one firing model needs to have range.
OK, now I know you didn't understand me, because the wound pool (despite being mentioned) has nothing to do with the logic of it.
Q: When making a Shooting attack against a unit, can Wounds
from the Wound Pool be allocated to models that were not within
range any of the shooting models when To Hit rolls were made (i.e.
half the targeted model are in the shooting models’ range, and half
are not)? (p15)
A: No.
The only thing the FAQ says, for sure, is that if "not any" (meaning none, but it's bad grammar and they omitted an "of") the weapons could reach a model, then none of the wounds can be allocated to it.
Does that mean, necessarily, that if SOME of the weapons could reach that model, that you can allocate all the wounds to that model, beyond that which could reach them? No it does not. Does it necessarily mean you cannot? No, doesn't say that either.
Did GW intend for the entire wound pool to be applicable to a model even if it was only in range of one weapon? Well, hell, I dunno, probably, if they thought that far, but I'm not sure they did. Until yesterday, I thought they "intended" for the entire wound pool to be applicable if any part of the unit was in range to start with, because frankly that's just easier.
If I was the TO, I'd probably say that if one weapon was in range, you can apply the whole pool, i.e. the same ruling as everyone else, but only because in the absence of a clear answer I'd default back to what it says in the BRB, which would have everything be in ragne if it was to start with anyway.
So we come to the same place. But what is driving me NUTS is that everyone is acting likes it's perfectly clear and obvious, if unexpected. But it's not, they're contradicting a negative (with bad grammar, too)--the only thing it says for sure is that if no weapon can reach a model, you can't allocate wounds to it. It gives no instructions beyond that.
Everything else is just assumptions you're making to make it work, which, y'know, does have to be done.
