Which document is NOT required for units to bring to the ASP for ammunition pick-up?

The correct choice highlights a document that is not necessary for units to bring to the Ammunition Supply Point (ASP) during the ammunition pick-up process. Understanding the purpose of each of the forms listed clarifies this.

DA Form 5515, typically used for documenting the condition of ammunition or for reporting ammunition discrepancies, is a part of necessary paperwork for ensuring accountability and safety during the ammunition handling process.

DA Form 581 is essential as it is the request for ammunition, serving to officially indicate which types and quantities of ammunition a unit is authorized to pick up.

DA Form 1687 pertains to the designation of an individual as an authorized agent of the unit; having this on hand confirms who is permitted to pick up ammunition on behalf of the unit.

DA Form 626, also important, serves to track ammunition issues and is important in the accountability of ammunition discharged from the ASP.

In this context, DA Form 5515 is the correct answer as it is not a mandatory document for the ammunition pick-up process, while the other forms play critical roles in ensuring the accurate and safe distribution of ammunition at the ASP.
