Which role involves direct responsibility for tactical employment and personnel management?

The role that involves direct responsibility for tactical employment and personnel management is that of the platoon leader. This individual is charged with overseeing the operations of the platoon, ensuring that tactical objectives are met while effectively managing the personnel within the unit. The platoon leader has a critical role in planning and executing missions, making strategic decisions based on situational awareness, and providing guidance and leadership to the members of the platoon.

In contrast, the team leader, weapons squad leader, and squad sergeant have specific responsibilities either focused on smaller subsets of the unit or particular functions within the platoon. While they play important roles in staffing, leading, and executing tasks within their respective units, the overarching responsibility for the entire platoon's tactical employment and comprehensive personnel management rests with the platoon leader. This position requires a broader scope of understanding and decision-making that encompasses the entire unit's capabilities and needs.
