What type of identification can serve as satisfactory evidence for an applicant's military service?

An official military identification card is the most appropriate form of identification for verifying an applicant's military service. This card is specifically designed to represent service members and their families, providing clear and direct evidence of active or former military status. It contains pertinent details such as the individual's name, photograph, and service branch, making it an unambiguous source of proof regarding military service.

In contrast, a driver's license, social security card, or passport do not provide specific information about an individual's military status. While these documents can establish identity and, in some cases, citizenship, they do not inherently confirm or detail military service. Thus, the official military identification card stands out as the unequivocal evidence required for validating military service in this context.
