As I keep repeating, including in the very post you just replied to, that is almost irrelevant - the modern imposition of tyranny, as we have seen it around the world, is not usually accomplished by armies and such. It is accomplished via goon squads and mercenaries and factions of "national guards" and special branches of the police. It is the Tonton Macoutes in Haiti, the Contra guerrillas in Nicaragua, that are typical. We have seen that in the US, with the KKK and the police forces of a couple of major cities. There are good reasons for that, from an ambitious tyranny's pov, but here we only need note the simple fact: freedom is well supported against intrusive government if one can deter the local KKK, the local police, etc. You don't have to worry about the military, especially in the US - that's not how it's done. Rifles and shotguns and handguns would have been - and would be - perfectly adequate deterrents to the KKK. That's one reason black people have been kept largely disarmed. Tyranny is not only profitable, but securely so - the vast wealth gained by strongman and plutocratic governments in even the poorest countries is proverbial. In the US it would be the stuff of legend. The lesson of looking around would be that the level of poverty at which a government can no longer afford weapons and soldiers is incapacitating starvation among the citizenry. So collapsing the economy would facilitate the powergrab, not interfere with it. Consider who is going to able to afford all those weapons and soldiers - at the new low prices - when the government has been bankrupted. The "establish a new government" part is quite unlikely to go as one would wish. That was routine when I was young - 4H programs http://www.4-hshootingsports.org , Boy Scout merit badge training sessions https://www.meritbadge.org/wiki/index.php/Rifle_Shooting , local police or sheriff department programs, often organized through the local high school, taught by military veterans. One routinely saw high school students bring their rifles to school and put them in their locker, in preparation for classes or examinations after school. The gun control/anti-hunting folks got rid of them, and if you try to bring them back you will face serious opposition from that faction. You would also face opposition from the large fraction of racially bigoted Americans who would not want to see black teenagers taught how to use firearms - the underlying factor in so many odd dysfunctions of American society, from health care to transit to housing to unions to judicial reform.
