Which of the following is NOT a basic responsibility of a Non-Commissioned Officer?

The role of a Non-Commissioned Officer (NCO) within the Army is pivotal, focusing primarily on the leadership, training, and welfare of soldiers. Among the basic responsibilities of an NCO, maintaining government property, training soldiers, and executing the mission are all core functions that directly relate to the NCO's role in managing personnel and ensuring unit effectiveness.

Managing the supply chain, while important in Army operations and logistics, is not typically classified as a primary responsibility of an NCO. This function is generally more aligned with roles in logistic units or supply chain management, where specific knowledge about logistics operations, inventory management, and procurement processes is required. NCOs are expected to understand and oversee aspects of supply management as it pertains to their unit and personnel, but it does not reflect the fundamental purpose of their rank which is predominantly centered around leadership, mentorship, and mission execution.

Thus, the correct answer identifies a responsibility that, while significant in the broader context of Army operations, does not fall directly within the basic duties expected of an NCO.
