Who leads a squad?

• A. Platoon guide
• B. Squad leader
• C. Platoon sergeant
• D. Company commander

Answer: (B)

At the smallest Marine unit, the person in charge is the squad leader. This role, typically held by a sergeant, is responsible for guiding the squad in all tasks, directing fireteam actions, and handling training, discipline, and welfare to ensure the squad accomplishes its mission under the platoon’s overall plan. The squad leader serves as the direct link between the two fireteams and the larger unit, making quick, on-the-ground decisions and maintaining cohesion during movement and action.

The platoon commander, usually a lieutenant, leads the entire platoon, with the platoon sergeant handling the enlisted leadership for the platoon. The company commander leads the company, which comprises multiple platoons. The platoon guide, when present, is a support role within the platoon—not the leader of the squad.
