Dear Mr. Hayworth,
Thank you for posting your request on History Hub!
Depending on when Bret K. Hayworth was in the service and which part of the U.S. Armed Services he served determines the location of his service records and the forms to request them. Please consult NARA’s web pages for this information at https://www.archives.gov/veterans/military-service-records/locations.
We hope this is helpful. Best of luck with your family research!
