Platoon leader

A platoon leader (NATO) or platoon commander is the officer in charge of a platoon. This person is usually a junior officer – a second lieutenant or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant. Some special units, such as specific aviation platoons and special forces, require a captain as platoon leader, due to the nature and increased responsibility of such assignments. Platoons normally consist of three or four sections (Commonwealth) or squads (US).
