Um! Thanks for the reply.
Your saying that smoke in a hex has no effect on combat. Only smoke between hexes does.
If this is correct I've been playing the smoke game wrong, forever. I alway though smoke added to the cover of any hex it's in which in my mind it rightly should do.
I've tried attacking in this situation both with and without and I seem to have more luck using smoke than not, by a long way. It's seem this is false then
