Which of the following is NOT a responsibility of a Platoon Commander?

The role of a Platoon Commander encompasses several key responsibilities that contribute to the successful functioning of the unit. While the Platoon Commander does indeed ensure that standard operating procedures (SOPs) are known and understood by their Marines, the specific act of enforcing them is typically not categorized as a primary responsibility.

Instead, the responsibilities lie in the strategic and tactical realms—developing training plans, conducting coordination with higher units, and supervising operations are all essential duties that directly affect the effectiveness and readiness of the platoon. Each of these actions requires a high level of leadership, planning, and decision-making aimed at ensuring the platoon meets its operational goals. Therefore, while supervising compliance with SOPs falls under the broader umbrella of a Platoon Commander's duties, it is not highlighted as a core responsibility like the other options.
