There is a decent sized movement going on that would probably play hell with this. Check out Oathkeepers.
Secondly, in this country, the pro-gubmint "entitlists" are not what I would consider highly trained in combat or arms. Those that already own the 100 million guns in the US lean to the other side of the fence. So, civilian on civilian, I don't worry too much. You don't pick up a military grade weapon and start dropping head-shots at a quarter-mile without some practice. CoD doesn't teach you anything about recoil, followup shots, and real tactics. I can not work up the worry from that scenario.
This differs from other countries where there is no real civilian armament. And I'm pretty sure this is the reason we have the Second Amendment in the first place.
Thirdly, I don't think that our military would fire on civilians. Some might, there are always a few. But our armed forces (active and reserve) are drag ass tired and war weary after a decade of groundpounding. To come home and fire on their neighbors, friends and family? I just don't see it. I in fact see that going real bad for a commander that ordered it. I see the same thing from LEO. Sure, there might be a few. But those that have sworn oaths to defend, we are by and large a pretty proud bunch. Honorably serving. Now BATFE, those guys I wouldn't trust if I had them handcuffed, disarmed, blind-folded, and at gunpoint.
Off topic, slightly.
While having one of many discussions on prior/current service and the changing political landscape, I have discussed something similar.
A small handful of us would take our decent sized armories to a more rural location with emergency everything (the owner is borderline EOTWAWKO prepper), but he has the biggest arsenal. We all meet up there with all of our families, supplies, and weapons and hang tight there. I'm not saying that a dozen or so people could stand up to a full scale military style assault, but I promise you that the average rabble would fare very poorly.
Personally, I'm not worried about arming the neighborhood. I only actually plan on arming each member of my own family with a long-gun and a side arm (that they are capable of using) and adequate ammo supplies to get us where we are going. The real trick is getting there before things got bad enough that you had to fight anything other than traffic getting where you were planning on going.
Anyone else gets milsurps or hand-me downs. Yes, that Mosin I handed you will do just fine. Just a little slower than the one I have, and with few rounds on hand.
