What documents must personnel provide as proof of authorization to receive ammunition?

The correct answer is rooted in the established protocols for munitions accountability within the military framework. Personnel must provide DA Form 1687, which is the Notice of Delegation of Authority, as it formally designates individuals who are authorized to receive ammunition. This document ensures that only those with the appropriate authority can handle such sensitive materials.

Additionally, Assumption of Command Orders clarify the leadership structure and roles within the unit, confirming that the designated personnel are recognized and empowered to manage ammunition logistics under command authority. This combination of documentation supports accountability and security in the handling of munitions.

Other options present various valid forms and certifications, but they do not specifically align with the requirements for proving authorization to receive ammunition as established in military guidelines.
