Which system provides access to service personnel records for Veterans discharged after specific dates?

The Defense Personnel Records Information Retrieval System is the correct answer because it is specifically designed to give authorized users access to the service personnel records of veterans who were discharged after certain dates. This system helps streamline the process of retrieving important records, ensuring that veterans, as well as those assisting them, can access the necessary documentation to support claims or benefits applications effectively.

While other systems mentioned may play roles in managing or archiving records, they do not directly provide the same level of accessibility to personnel records as this system does. For example, the National Archives and Records Administration does maintain historical records but is not focused solely on retrieving up-to-date personnel files for recent veterans. The Defense Financial Records System deals with financial transactions and may not contain personnel records. The Personnel Information Exchange System is used for sharing information among various defense entities but does not serve the specific function of retrieving veteran personnel records like the Defense Personnel Records Information Retrieval System.
