WWI TO THE PRESENT · RESEARCH GUIDE
Find the person
behind the uniform.
Start with a name or a clue. Request the military personnel file, read what it actually documents, and use unit records to build a fuller story.
01 · PREPARE
Write down what you know.
A complete name as used in service is the best starting point. Add the branch, approximate service dates, date and place of birth, service number, and last unit if known. Record where each clue came from. If you only have a uniform, photograph labels, names, laundry marks, patches, and any paperwork found with it. A number or patch alone does not identify its wearer.
If details are missing
Start with family papers, photographs, obituaries, local newspapers, draft registrations, and cemetery information. Genealogy sites can help locate clues, but compare their indexed names and dates with the actual record. The National Archives’ History Hub ↗ can help you frame a research question.
Have a challenge coin?
Photograph both sides and the edge. Transcribe the exact unit name, motto, dates, operation, location, and any person’s name. A coin may point to an organization or event, but it can be presented, traded, purchased, or passed down. It is not proof that its owner served in that unit, deployed to that operation, or earned an official medal. Compare the design and date with the issuer’s history, then seek a named personnel record or other evidence.
The familiar WWI origin story is not established by written records; the Department of Defense describes several competing traditions. Challenge coin history and its uncertainties ↗.
02 · REQUEST
Ask for the personnel file.
The Official Military Personnel File (OMPF) is the core record of an individual’s service. Most files are not fully online. Use the National Archives request page ↗ to choose the appropriate route, or use Standard Form 180 ↗. Request the complete file when available and ask for the separation document. The request page has current instructions, identity requirements, and fees.
Who can access it?
Files become archival and generally open to the public 62 years after separation; copying fees may apply. More recent files have access restrictions. Veterans and qualifying next of kin have different request options. Check the National Archives access rules ↗ before submitting; do not post private service numbers or documents publicly.
Which discharge form?
A DD Form 214 is common for more recent service. Earlier services used other separation forms, including Army WD AGO 53-55 and Navy, Marine, and Coast Guard equivalents. Do not assume a WWI or WWII veteran has a DD 214. Compare separation forms and fields ↗.
03 · INTERPRET
Read each line as a clue.
Start with the name and service number, entry and separation dates, grade, occupation or specialty, units and duty stations, foreign service, and listed awards. Make a timeline with the document’s exact wording. A separation paper summarizes service; it is not a complete diary. An OMPF can hold assignments, training, qualifications, awards, and administrative actions, but it generally does not list every battle a person personally experienced. What personnel files contain ↗.
Example: a division patch on a coat
The patch suggests a unit connection. A dated assignment in the personnel file or a named roster can support when the person served with that unit. A division’s campaign history alone cannot prove that this individual participated in every campaign.
04 · CONTINUE
If the file is missing or incomplete.
The 1973 fire damaged or destroyed millions of Army and Air Force personnel files. A “fire-related” response is not the end of the research. Ask the records center about alternate record sources ↗, then follow named units, dates, and locations into rosters, morning reports, orders, award citations, and local collections. Read the National Archives’ fire history ↗.
Morning reports and unit rosters ↗ can narrow an assignment or movement, but access depends on service and date. Some archival records require a visit to the St. Louis research room or an independent researcher; later records may be restricted. Read the current access page before making plans.
Bring the evidence together
Keep four columns in your notes: what you observed, the possible meaning, the dated source, and what remains unproven. Revisit the insignia only after checking the person’s service dates.
