The glass backbone: Why the Army's logistics will break in the next war 12 days ago
When the hordes of Genghis Khan conquered Asia, how did they deal with logistics? Answer - They didn't. Everything they needed came from the horse. Transportation and food in the form of blood and milk.
How could a modern army replicate this? Mobile nuclear powered bioreactors that could create food? Mobile 3d printers that could consume local materials to create ammunition? An interesting thing to think about.
