Platoon (military unit)

Organization and roles

Typical platoon organization groups two to four squads or sections under a single leader. The officer in charge is often called a platoon commander; a senior non‑commissioned officer acts as second-in-command and handles many of the practical leadership duties. A platoon may include a small headquarters element for communications, planning, and logistic support, plus specialized teams such as weapons, reconnaissance, or vehicle crews where required.

• Platoon commander: tactical control and decision-making
• Platoon sergeant or equivalent NCO: discipline, administration, and training
• Squads/sections: the basic maneuver teams
• Support elements: communications, weapons, or vehicle crews

History and terminology

The word "platoon" derives from a European term for a small group and entered modern military usage as armies formalized intermediate command levels. Over time the size, equipment, and exact composition of platoons have varied between nations and eras, reflecting doctrine, technology, and mission requirements. Different armies use alternative names such as "section" or retain historic distinctions in how subunits are numbered and employed.

Uses and notable distinctions

Platoons serve as the link between company-level command and individual squads. They provide flexible, self-contained teams capable of independent action or coordinated operations within larger formations. Variants include dismounted infantry platoons, armored vehicle platoons, and specialist platoons for engineers or signals. A key distinction is that a platoon is usually commanded by an officer, whereas squads are normally led by non‑commissioned officers.
