The Constitution is flexible in that the people can give more power or different powers to the federal goverment or revoke them at any time and for any whim. It was not designed to work the other way around, where a government can assign itself more powers and revoke the rights of the people.

Therefore, the people need parity with the government forces at a minimum. There were not to be standing, professional armies but militia. And everyone owning firearms increases that effectiveness of defending individual rights from all comers and in all corners.

Green Berets probably know better as spec ops are often (especially Green Berets) with making friends and political inroads with 'rebels' in various countries. Anyone who looks into how and why our country was founded would know, however.

Kudos.
