What document type contains operational procedures for the management of ammunition?

The correct answer is the Army Regulation (AR) because these documents are specifically designed to provide official guidelines and procedures for various operations within the Army, including the management of ammunition. Army Regulations outline the responsibilities, processes, and safety protocols necessary to ensure effective and safe ammunition management. This is crucial for maintaining operational readiness and protecting personnel and equipment.

On the other hand, the Ammunition Safety Manual primarily focuses on safety aspects and risk management related to ammunition handling and storage, but it does not encompass broader operational procedures. The Field Manual (FM) serves as a reference for tactics, techniques, and procedures in military operations, which may include ammunition but does not specialize in management protocols. Technical Orders (TO) provide detailed instructions on equipment operation and maintenance, which may include ammunition systems, but they are not focused on the overarching management procedures like Army Regulations are. Thus, AR is the most accurate choice for the management of ammunition operational procedures.
