The fact that nato can sock-puppet a dead 2nd world country to defeat Russia suggests that the deciding factor in combat now and going forward isn't the fighting spirit and bad-assery of the soldier's mind and body, but instead a function of Fast production lines, of Robotics, computer vision, data processing, eyes in the sky, just in time analysis, nanotechnology and speed of adaptation and software code in computers, drones and all the rest.
Nato is Animating a dead corpse to beat 13 timezones of Russian fist with its own severed limbs.
The perfect tool for the job in time, saves 9.
The principal job of a soldier in the far future will be jumping out of a plane, landing, then taking fifty paces in an unforgivable combat zone, tapping an internet End-Rod into the ground, waiting for the solar pane and p2p laser to autotune with a green light, then repeating.
