What form provides instructions for items requiring "Signature Service"?

The correct answer is related to the specific role of the DD Form 1387-2, which is designed to accommodate items that require "Signature Service." This form serves as a crucial part of the shipping and transportation documentation process, as it provides detailed information about certain items along with a requirement for a signature upon delivery. This is essential for tracking accountability and ensuring that items are delivered correctly and securely.

In contrast, the other forms mentioned serve different functions. DD Form 1385 is primarily used for reporting cargo manifests, which lists cargo items but does not specifically dictate signature requirements. The Cargo Manifest itself is a general narrative listing of all cargo being transported and doesn’t provide specialized instructions for items needing signature or receipt acknowledgment. The Custodial Transfer Form indicates the transfer of custody for items but does not specifically relate to signature service requirements. Thus, DD Form 1387-2 accurately fulfills the requirement for items needing "Signature Service."
