The oldest tech in warfare: a person, a weapon, and legs that can say no.

means Soldiers who fight on foot, as opposed to those on horseback, in vehicles, or in the air.

from From French infanterie, rooted in Italian infante — literally 'infant' or 'youth,' which came to mean a foot soldier, the lowest-ranking, youngest grunt in the military hierarchy. The same root gives us 'infant' the baby; the foot soldier was the army's junior rank, the one sent to walk while officers rode.
