A Growing Concern — What Are They Practicing For?

SEE HERE  Another surprise exercise wakes up an American city scaring the inhabitants.  The question is what are all these exercises all about and why are we suddenly seeing the U.S. military practicing as if they are going to seize American cities?  Our military is for defense and not civilian control.  Americans are supposed to be a free people not one under the subjugation of a central oligarchy of the anointed far left which is the way things seem to be going.  At least there should be some advance notice if they're going to practice tyranny over our cities.
