What a weird historical anomaly. I really don't know what else to say.
In the martial arts, one learns a number of possible countermoves against different types of possible enemies. These practice battles are done over and over until they become instinct. Likewise in the Earth Battalion all plausible engagements are war-gamed until each soldier has the routine cold. In this way the battalion can operate in the absence of commands from its leaders, who may be out of touch, because of the new realities of modern warfare.
[A chart compares "martial art stances" (e.g., prepare left, block left, en garde, prepare right) to a flowchart reading:]
If you are overrun -- move to the nearest road junction, take control of the buildings, wait for his towed artillery, destroy all you can… till you have lost an offensive punch, then exfiltrate [sneak out] or surrender to save life.
All warrior monks, but an interdependence of New Age skills as well.
