**If the intent was to cut off power, take out the lines leading out from the plant.**
If you wanted to control a power plant, would you knock down power lines that may take a week or more to repair (especially if more than one wire tower is destroyed) or simply gain control of the switch boxes?
I would try the latter first.
Russia has control of the plant and are laying explosives now per reporting from WTAM 1100.
Given the chance of things going awry by trying to do a heavy assault at the plant, I’d find ways to interrupt the lines at a distance. Perhaps “interrupt” is a better wording than “take out”.
Now, if those control boxes can be taken control of (not “taken out”) by a light assault, that’s a different matter. Which I noted. Tanks are not a “light assault”, in my book.
