Your comments reflect my thinking, a few hundred guys could bring the grid down over night. Air liners filled with troops could land at air ports, roll-on roll offs could be filled with armor, they could preposition material in anchored ships that look like they are waiting for normal unloading. They could add the use of EMP, shoot down our communication satellites and cut the under sea cables. Right now the guys on base don’t even have guns, what are they going to to? One person with a pistol is more then they can handle on a base.
