Identify the record you need
Military service records can help document assignments, qualifications, awards, and separation. An Official Military Personnel File is mainly an administrative record, not a detailed narrative of every battle or operation a person experienced. Before making a request, identify the practical question you are trying to answer. A separation document, a medical record, and a unit history serve different purposes.
Use the official route
The National Archives provides guidance on requesting service records and explains that the location and availability of a file depend on service history and separation circumstances. Some material may be accessible through official online services, while other records require a request. Follow the current instructions for the relevant record type rather than assuming every file is held in one place or is already digitized.
Keep a simple request log
Retain a copy of what you submitted, the date, and any official reference number. Provide sensitive identifying information only through the authorized process. If a record is needed for a benefit or administrative matter, ask the responsible agency which document it actually requires before ordering several different files. For family research, separate a request for someone’s personnel record from an investigation into the history of their unit. These distinctions can save time and make follow-up questions more precise. This guide provides an orientation; it does not establish anyone’s access rights or guarantee that a particular document will be available. The official custodian’s guidance controls the individual request.
