so during the live stream i went ahead and ask about smoke tokens and of course multiple smoke tokens
Per Alex Davy " Smoke tokens give you cover 1 full stop. so if your in a set of woods with smoke you wouldn't improve your cover." "the only thing that improves your cover is suppression."
so unlike what the rules where it improves your cover by 1. it gives cover 1 (light cover) not improves it.
