Sorry, I misread that in my last post. It's still not going to happen this way. The JBT's will be quartered in compounds surrounded by mines and concertina, probably looking a lot like a Fire Base from the Vietnam era. They will rarely be found alone. Look read these books: EFAD and you'll get the right idea.
The jackbooted thugs can’t all move onto federal property, it won’t happen. They live among us, and will continue to do so, so a firebase is not a correct comparison. They want to live normal lives, and it could get risky crossing the parking lot at Target. Or playing golf, or fishing. They don’t live in body armor.
One strategy is to have a couple of guns meant to be given up, an old revolver or two, say. And if they are taken, take that as a declaration of war.
