1630–40; earlier plotton < French peloton little ball, group, platoon, diminutive of pelote ball. See pellet, -oon

Explanation

A platoon is a military unit made up of squads. If you’re in a war zone, you might see a platoon of soldiers guarding a checkpoint. Military branches such as the army, navy, air force, or marines are broken down into smaller groups. One is a platoon, which is part of a company and made up of squads. A platoon usually has its own headquarters and is under the command of a lieutenant. In a war, platoons will be stationed in places according to strategy — the platoon might be attacking or defending. Platoon (1986) is also the name of a war movie about Vietnam.
