Which form is used by unit commanders to delegate authority for specific personnel to receive ammunition?

The form used by unit commanders to delegate authority for specific personnel to receive ammunition is the DA Form 1687. This form serves as a formal document that allows commanders to designate individuals who are authorized to pick up and handle ammunition on behalf of the unit. The use of this form is important for maintaining accountability and ensuring that only properly authorized personnel have access to potentially dangerous materials such as ammunition.

DA Form 1687 ensures that there is a clear record of who has been authorized to handle the ammunition, promoting safety and compliance with regulations regarding ammunition management. This process helps to mitigate risks and adhere to established protocols within the military environment.

The other forms listed serve different purposes: DA Form 3151 is used for the ammunition transaction report, DD Form 626 is for inspecting military vehicles for the transportation of explosives, and DA Form 581 is used for requesting and dispensing ammunition. Each of these forms plays a crucial role in various aspects of military logistics, but none fulfill the specific function of delegating authority for personnel to receive ammunition like the DA Form 1687 does.
