infantry

This term carries a heavy association with grit, endurance, and direct physical confrontation. It evokes the image of the frontline, where the most grueling and dangerous combat typically occurs, contrasting with the distance provided by artillery or the mobility of cavalry and armor. In modern professional contexts, it is often used to describe the backbone of an army. Outside of military settings, it can be used ironically or metaphorically to describe people who perform the most basic, repetitive, or difficult tasks at the bottom of an organizational hierarchy.
