What must DDAs ensure about unused munitions?

The correct answer emphasizes the responsibility of Defense Department Activities (DDAs) in managing unused munitions, particularly those deemed unserviceable. Proper disposal is crucial for safety, environmental protection, and compliance with regulations. It ensures that munitions that cannot be used effectively do not pose a risk to personnel or the environment.

While ensuring that munitions remain in service for future conflicts, labeling for inventory replacement, and conducting regular safety inspections are all important aspects of munitions management, they do not directly address the immediate need to handle unserviceable munitions. The proper disposal of these items is a primary concern to prevent any potential hazards, including accidental detonation or environmental contamination, which reinforces the importance of understanding and following strict protocols for handling such materials.
