They will use National Guard troops to enforce any new ban/confiscation/registration laws that people will try to ignore (that is NG troops from different states coming to your state so there will not be sympathy from your home state NG members). NG units will have no difficulty and no sympathy, taking out American families and towns if necessary. They will do as ordered.

That's when the governor calls up their NG units and orders them to defend state citizens against what rapidly turns into an invasion.
