With all due respect, civilian weaponry doesn’t match military firepower.
Civilians don’t have:
Carrier battle groups.
Stealth bombers.
Nukes.
Predator drones w/Hellfire missiles.
RPG’s.
Howitzers.
Tanks.
TOW missiles.
Apache attack helicopters.
etc., etc.
I wouldn’t count on the military siding with civilians. Some units may, but if push really came to shove, the bulk of the military will side with the government. And if that happens, and they turn full-on against the civilian population, civvies don’t stand a snowballs chance in Hell.
With all due respect, the British Army has all the hardware you list, but could not defeat a small band of its own subjects in Northern Ireland. Using the tactics pioneered by Michael Collins in the 20’s, civilians are not helpless against their government.
Dang, and I was saving up for a Howitzer.
