I think that was my point. The gray zone and extensively trenched frontlines in Donbass are the hot example of a border, around industrial and mining cities and urban areas. So they are an extreme example, if you like. But then, so is the mass-migration occurring on the border (s) an extreme.
However, it is my opinion that warfare has gone almost medieval in the way it is suddenly carving itself into the face of the Earth along natural boundaries, high spots for communication purposes, and the precise targeting that comes with it. It is suddenly the case that trampers find ancient theodolites and tunnels dug by early Christians. The patterns and maps of our civilizations were bold and clear in the twentieth Century, as if someone drew it with a set of colored pencils (They prolly did, akshully, given that they halved or quartered some peoples arbitrarily and granted themselves sovereignty over impoverished tribesmen to enrich themselves, etc.). Some of their designs even had Roman squares, starforts, etc. to project their power. Now, the best hide is within the Earth, like a Pict.
The all-seeing live-streamed and connected generation is hitting 3d printers with wondrous materials. They can set up in any bunker, tunnel, cave or whatever, with a wee solar panel or even a generator. The more invisible from above, the better. A tiny camper-van painted in camo, with some netting. Gee. I don't know, and a golf-cart with cope-netting?
Cappadocia anyone?
I believe there exists already a tunnel network under the border.
