"I don't see how the presence of it would make artillery obsolete."
It doesnt, just yanking chains. In that sort of mood today. Monday... Re the options to take me offline..... OK, I'd use a backup power supply (And employ better guards next time).

Meanwhile, your Arty boys and girls are sitting on their hands, waiting for ammo. Eating flumps.
