Which of the following medals is not listed among the awards tracked in the vPC?

The Defense Distinguished Service Medal is not included among the awards tracked in the vPC (Virtual Personnel Center). The vPC primarily focuses on specific awards that are common across various branches of the military, particularly those that are directly linked to service and operational accomplishments. The other listed medals, like the Combat Readiness Medal, Air Medal, and Army Achievement Medal, are more regularly associated with the records kept in the vPC due to their relevance to individual performance and mission readiness within the military community. The Defense Distinguished Service Medal, however, is typically reserved for senior leaders and recognizes exceptional service by high-ranking military officials, and thus it is not tracked in the same manner as the others in the vPC system. Understanding the distinction in how various awards are categorized and tracked is crucial for recognizing individual contributions to military service.
