Mission 14: Reporting for Duty — Military Records and Your Ancestor's Service File
I found it in a cigar box at the back of a closet that smelled like cedar and forgotten decades. A single sheet of paper, folded in thirds, so brittle at the creases that it nearly came apart in my hands. It was a discharge certificate—dated 1919, issued to a man whose name I’d only ever seen penciled into the back of a family Bible. That one document led me to a pension application, and that pension application led me to depositions from neighbors, a marriage certificate I didn’t know existed, and a physical description so detailed I could have picked him out of a crowd.
That’s the thing about military records. They don’t just tell you someone served. They tell you who that person was—down to the color of their eyes, the scar on their left hand, and the name of the wife waiting back home.
So consider this your official enlistment. Welcome to Granny’s research corps, recruit. Time to report for duty.
Your Orders: The Three Records That Matter Most
Not all military records are created equal, and you don’t need to master every archive in the country to get results. Focus on three record types, and you’ll cover more ground than most researchers ever do.
Service records—officially called Official Military Personnel Files, or OMPFs—document your ancestor’s entire military career: when they enlisted, what unit they joined, where they were stationed, and whether they were wounded, captured, promoted, or court-martialed. These files may also contain date and place of birth, civilian occupation, marital status, and a physical description. Post-World War I service records are held at the National Personnel Records Center in St. Louis. Earlier records are at the National Archives in Washington, D.C.
Pension records are where the real treasure is buried. When a veteran—or more often, a veteran’s widow—applied for a government pension, they had to prove their case. That meant submitting marriage certificates, birth records, family Bible pages, letters from neighbors, and depositions that read like small-town gossip transcribed under oath. A single Civil War pension file can run to hundreds of pages. If you find one, clear your afternoon.
Draft registration cards are the beginner’s best friend because they cast the widest net. The World War I draft covered roughly 98 percent of American men between 18 and 45. The cards record birth date and place, spouse or next of kin, employer, and a physical description. World War II brought its own draft, including the “Old Man’s Draft” for men born as far back as 1877. Both collections are digitized and searchable on FamilySearch, Ancestry, and Fold3.
Know Your Base: Where to Look First
FamilySearch is free and hosts digitized World War I and World War II draft registration cards. Start here. Search by name, narrow by birth year, and see what turns up.
Fold3 is a subscription military-records platform owned by Ancestry. Many public libraries offer free access through Fold3 Library Edition, so check your library’s digital resources before paying.
The National Archives Catalog lets you search for records and sometimes view digitized images. For records that aren’t online, you can order copies. Pre-World War I records are held in Washington; post-World War I records are at the NPRC in St. Louis. Military personnel records become publicly accessible 62 years after separation; before then, only the veteran or next of kin can request them.
Don’t overlook state archives. State Adjutant General records, National Guard files, and state bonus records can fill gaps that federal records miss—especially for veterans of state militia units.
The 1973 Fire—and Why It’s Not Game Over
On July 12, 1973, a fire at the National Personnel Records Center in St. Louis destroyed approximately 16 to 18 million military personnel files. No backup copies existed. For Army veterans discharged between 1912 and 1960, roughly 80 percent of the records were lost. For certain Air Force veterans discharged between 1947 and 1964, the loss was about 75 percent.
It’s a gut punch, but the trail didn’t go cold—it just got more creative.
The NPRC has spent decades reconstructing lost files using alternate sources. A request can trigger a search of final pay vouchers, Army morning reports, VA claims files, Selective Service records, and state-level copies. Some partially burned “B Files” survived with fire and water damage and can still yield usable information.
The lesson is simple: always submit the request, even if you think the record was destroyed. Draft registration cards, pension files, and state records were stored elsewhere and weren’t touched by the fire.
Your Assignment
Pick one ancestor who served in the military. It doesn’t have to be a combat veteran—peacetime service counts, and so does a draft registration even if they were never called up. Determine which conflict period they fall into, then search FamilySearch for their draft card or submit a request to the NPRC for their service record. Just one record. That’s your mission.
You’ll be surprised how much a single document can tell you about a person the family barely remembers.
Granny says:
“Every service record is a promise someone kept—to their country, to their family, and now to you. Honor the person behind the paperwork. That’s what this work is really about.”
