Theyd need forces not from the US unless they wanted to start carpet bombing their own families.(zero mil experience here so take it for what its worth)
-I think drone usage will be cranked up to 11 going forward. That will be tough for average Joe's to counteract.
-If US troops are squaring off vs civilians on US soil, that means that things have gone so far off the rails that the Feds are in a fight for their very existence. The RoE in that situation are not going to be the same as when .mil is dealing with browns on the other side of the planet. Theyll carpet bomb the suburbs if thats what they believe will keep them out of a noose.
Also you can own drones too
