How can I obtain records for someone who served in a different branch?

To obtain military records for an individual who served in a different branch of the United States Armed Forces, one must first identify the correct branch in which the individual served, as each branch has its own process for maintaining and providing access to records. Generally, the most comprehensive source for these records is the National Archives and Records Administration, which holds the Official Military Personnel Files for many service members. When seeking records, it is important to gather as much information as possible about the individual, including full name, date of birth, service number, and the specific branch of service. This information will facilitate the request process. Requests can often be submitted online, by mail, or sometimes via other specific contact methods depending on the branch. Each branch may have different requirements for verification, particularly if the records are deemed sensitive or if the individual is still living. It is advisable to review the specific web pages associated with each branch of service to determine their procedures and current contact information.
