“On the future battlefield, if you stay in one place longer than two or three hours, you will be dead,” Army Chief of Staff Gen. Mark Milley says. “That obviously places demands on human endurance.”
With units in constant motion far from friendly forces, “being surrounded will become the norm,” continues Milley. There will no clear front line, no secure supply lines, no big bases like Bagram or Camp Victory with chow halls, air-conditioning, and showers. With enemy drones and sensors constantly on the hunt for targets, there won’t even be time for four hours’ unbroken sleep. So, says Milley, “being seriously miserable every single minute of every day will have to become a way of life.”
[S]oldiers will struggle “just to survive” on a battlefield more lethal than anything we’ve seen “since at least World War II,” said Milley. To avoid being detected and targeted by precision weapons, soldiers — and Marines and even ships — must split into small units and keep either on the move or under cover. Static bases will be sitting ducks, and supply convoys will be so dangerous that they might be entirely automated, so units will be largely on their own, purifying their own water and 3D-printing spare parts for broken gear.
