pl: battalions
This term carries a strong sense of rigid structure, discipline, and collective strength. It evokes the image of a cohesive unit moving in unison, where individual identity is secondary to the goals of the group. While it originates in military contexts, using it in civilian settings usually adds a layer of intensity or overwhelming scale to the description.
When used outside of the army, the word often implies a sense of urgency or a coordinated assault on a task. It suggests a force that is not just large, but strategically organized to achieve a specific victory or objective, distinguishing it from a mere crowd or a random gathering.
Countable when referring to specific military units or organized groups of people.
