Which document ensures proper accountability in shipping munitions within the Army?

The Department of Defense (DD) Form 1149 is specifically designed for the accountability and documentation of shipping and receiving munitions. This form serves as a critical record that tracks the movement of ammunition and explosives, ensuring that all items are accounted for during transport. It provides pertinent details such as quantities, serial numbers, and destination, which are essential for maintaining the integrity of munitions management.

Using the DD Form 1149 helps to prevent discrepancies and ensures compliance with safety, security, and operational regulations regarding munitions handling. This accountability is crucial for logistical operations within the Army, as it helps to ensure that all munitions are properly documented and monitored throughout the entire shipping process.

Other documents and logs mentioned may play significant roles in munitions management and operational readiness, but the DD Form 1149 is uniquely focused on the shipping aspect, making it the correct answer in this context.
