Which of the following is NOT a responsibility of NCOs?

The correct choice indicates that developing policies is not typically a responsibility of NCOs (Non-Commissioned Officers). NCOs primarily focus on the direct management and training of soldiers, ensuring they adhere to established standards, and providing mentorship to foster personal and professional growth. While they do have some influence on policies through feedback from their experiences and interactions with soldiers, the formal creation and development of policies generally fall under the purview of higher-ranking officers and command staff. This delineation allows NCOs to concentrate on their essential roles, ensuring readiness and operational effectiveness at the unit level.
