Yes I knew it didn't apply to National Guard units, but wasn't aware there were a significant number of NG units trained to that level on call for such missions. Does every state have Ranger or other SF units?
I'll defer to your experience and expertise relative to the feasibility infiltrating a small force for intel gathering, but I would think a hostage rescue mission would be a different story.
Not every state, there's a few RANGER units and a few S.F. units, but they are strategically placed so that the majority of other states border them..
Hostage rescue could be a differant story, but that would depend on the size of the opposing force.
