The sort of person who needed to be shot at by the authorities because he or she was committing violence, or threatening to, with edged weapons, was unlikely to submit meekly to advances in the technologies used to enforce civil order. Directly they began to develop countermeasures, which, of course, then needed to be surmounted by the engineers in turn. If an ambot, for example, could be fooled into believing that it had missed its target or struck something that was not a human, it could be rendered nearly harmless. Camouflage changed its purpose from fooling the human eye to fooling the electronic brains of ambots. Armor was no longer made to stop extremely fast pieces of lead. Its purpose now was to protect the wearer from the invasive strivings of ambots. Warriors became living, moving fortresses under siege of multiple ambots that often used swarm tactics to find a way inside before their batteries ran down. The old tactical calculus of projectile warfare changed in other ways too. Katapults and botmo that had been captured by the enemy, or that had simply fallen to the floor and been picked up, could be rendered inert and useless by digital means. Some of them would try to find their way back to their masters, and so battle zones in which a lot of botmo had been expended tended to look as though they were infested by army ants as spent ambots attempted to swarm back toward the combatants who had fired them.
