I would hope the day never comes too and I doubt our troops would follow orders to attack citizens but American Citizen must use any means necessary to protect our freedoms if that fateful day ever arises which again I pray it never does.
Our current military might not attack citizens; however, with demographic trends, the future make-up of our military, i believe, will be composed of folks who would love nothing more than to turn their guns on the American public, which is why for the 1st time in my life as someone who has been traditionally pro-military, loved the Reagan build-up in the 80s, etc., now support gutting our military.
The military will follow orders.
