Lol!
I recall the northeast blackout.
I also recall wondering if it was a test to see our reactions.
Also recall some claiming it was “impossible” to attack the powergrid.
Well, considering that the SUN can attack our power grid, I wouldn't listen to them.
The power grid is indefensible.
In the event of a civil war it will be down for the duration.
Twenty teams...or cells. Five per team. Each assigned to a geographical area so the whole of the East Coast is covered. One hundred men.
Two men on each team have become proficient with a .308 rifle and scope. They scout the power sub stations in the area.
The entire operation is coordinated by cell phone. When the "Go" signal is received from a central coordinator, each team puts several rounds into the transformers at these stations. Within minutes, the whole of the East Coast is in the dark for a decade.
