A large military unit made up of several smaller companies, usually commanded by a lieutenant colonel. Informally, it can also mean a large number of people or things.
It comes from French “bataillon,” from Italian “battaglione,” a large group of soldiers, from “battaglia,” battle. The root is related to words for beating or fighting.
A battalion is literally a “battle-group,” a chunk of the army sized for serious fighting. When someone jokes about “a battalion of problems,” they’re turning their troubles into an organized army marching at them.
“Battalion” comes from military contexts that historically excluded women from combat and command roles, reinforcing a male default in discussions of soldiers and officers. Language about battalions often implicitly assumed all-male units.
When referring to personnel, use gender-neutral terms like “soldiers,” “service members,” or “troops,” and avoid assuming that members of a battalion are men unless the historical context requires that specificity.

Women have served in and led battalion-level units in many modern armed forces, contributing in combat, logistics, intelligence, and command despite longstanding institutional barriers.
