If we were to designate 10 miles on both sides of the border, all along its length, to be an artillery training range, then we could practice Corps level massed artillery fire and Time on Target fires to return the scumbags to a distance of at least a day’s walk back to the border.
Good idea, but it would take some significant relocation of resources. I’m at Fort Bliss now, right on the border at El Paso. Juarez is really big and right there on the border. I’m not sure where the heaviest crossing areas are—maybe AZ? That’s a haul for a DIVARTY unit, even a BCT. Certainly not impossible, but it would take a minute and cost a pretty penny.
