The US power grid can be taken down by a series of “surgical strikes” with the exception of the Texas grid. By surgical strikes, I mean a few marksmen (US army-tier Marksmen–the minimum requirement) hitting certain spots on the grid would fuck a lot of the military and government because they need the grid more than Bubba and his friends do. Additionally, while all government agencies have backup generators, they will be hard pressed dealing with the resultant looting and other madness that would come with power outages. This would effectively create another front for the military. It would also turn the people against the government more quickly and paralyze the government’s propaganda machine. Worse still–the key points of the US power grid are publicly obtainable information, and not only are the points too many to be effectively guarded, they are not guarded anyway.
