Nanomachine

Five years after the Big Shell Occupation, AT Security succeeded in making nanomachines even more complex and widely-used. The range of users was extended to include the regular armies of allied powers such as US military personnel, as well as PMC soldiers and public organizations such as police agencies. Nanomachines, which in the past were designed to control and manage an individual body, were no used as a tool to control a group. In the nanomachines used in the military battlefield control system, "Sons of the Patriots (SOP)", the user's ID is embedded, which in turn is used to perform ID authorization for system-managed firearms and other such devices. Nanomachines are designed for use at a pressure of 1 atmosphere. Therefore, in low atmospheric environments such as high mountains, they will malfunction and the secretion of neural substances will increase, due to changes in the concentration of oxygen in the blood. Consequently, PMC soldiers in the mountainous regions of South America head into battle in a state of intoxication due to excess secretion of neural anesthetic by nanomachines.
