What is required to be in your possession at all times while serving as a mail clerk?

The requirement to carry DD Form 285 at all times while serving as a mail clerk is primarily due to its function as a United States Department of Defense identification card. This form serves not only as proof of identity but also as verification of the individual's authority to handle, process, and distribute mail and packages within the military or related government logistics environments. Being in possession of this form helps ensure the security and integrity of the mail system.

In many military and government operations, having the proper identification is crucial for maintaining operational security, as it provides peace of mind for both the mail clerks and the individuals entrusting their correspondence to the postal system.

Other forms like DA FORM 7698, FC FORM 2996, and DA FORM 3955, while they may serve specific purposes related to military operations or mail processing, do not fulfill the same identification role, which is vital in maintaining trust and accountability throughout the mail handling process.
