Relationships built in the military can be strong, especially when they are forged during wartime. The records of those who served and the conflicts in which they fought are matters of public record. These records are now kept primarily online and are easily accessible to the public. If the name of the veteran who you are trying to find is unusual, the name may be enough to find him, but if the name is more common, additional information such as date and place of birth will help you to identify the correct person.
Register with the Korean War Veterans' Registry. Check the name of the person who you are trying to find against the database there.
Contact military reunion associations if you know the unit that the veteran belonged to. The National VETS archive has a list of over 12,000 reunion organizations including those for veterans of the Korean War.
Visit the Korean War Project website where you learn about the history of the conflict as well as refer to their page on Tiger survivors.
