19. Genghis Innovated the Corps Concept
Genghis Khan’s military innovations also included the equivalent of modern army corps operations. His Tumans of 10,000 warriors, which were powerful enough to take on significantly larger enemy formations, usually operated independently, marching separately to sweep across and devastate wide swathes of enemy territory. They were kept in contact with each other and with army commanders in charge of two or more Tumans by a steady stream of message bearing couriers. If a Tuman made contact with an enemy force too big to handle on its own, the other Tumans could quickly be called in and concentrated into an army.
