What provides proof of delegation of authority to receive ammunition?

The correct answer is based on the role of DA Form 1687, which is specifically designed to document the delegation of authority for personnel to receive ammunition. This form is critical in ensuring that only authorized individuals have the permission to manage and account for ammunition within a unit, thereby maintaining accountability and security of these materials.

DA Form 1687 includes necessary information such as the names of those granted authority, their positions, and the specific types or amounts of ammunition they are authorized to receive. By completing this form, a unit can clearly outline who is responsible for receiving and handling ammunition, which is essential for compliance with military regulations and effective logistical operations.

In contrast, the other forms mentioned serve different purposes. DA Form 5790 pertains to a variety of logistical tasks, but not specifically the delegation of authority for ammunition. DA Form 581 TAR is primarily used for requisitioning ammunition and tracking its movement, rather than formally delegating authority. DA Form 5692 is related to unique military logistics topics but does not address the proof of delegation necessary for receiving ammunition. Thus, DA Form 1687 is the appropriate choice for documenting authority in this context.
