What is the role of the platoon sergeant?

• A. The top sergeant in a platoon
• B. The platoon leader
• C. A junior officer
• D. The medic

Answer: (A)

The platoon sergeant is the senior noncommissioned officer in a platoon, serving as the top enlisted leader and primary assistant to the platoon commander. This role centers on keeping the platoon trained, disciplined, and ready by directing day-to-day operations, overseeing the execution of orders, and mentoring junior Marines. The platoon sergeant coordinates with squad leaders and other NCOs to ensure accountability of personnel and equipment, conducts inspections, and enforces standards of safety and performance. This position is held by a seasoned NCO, not a junior officer, and is distinct from the platoon leader, who is typically a lieutenant or other junior officer in command of the platoon. The medic is a specialty role focused on health care for Marines, not the overall leadership of the platoon.
