To be eligible, you must be a male descendant (includes stepsons and adopted sons) of a member of The American Legion. 

 You would also be eligible to join the Sons of The American Legion if you are the male descendant (stepsons and adopted sons included) of a veteran who died in service during World War I, World War II, the Korean War, the Vietnam War, Lebanon, Grenada, Panama, or the Persian Gulf War (see specific time periods for service during these conflicts).

 You would also be eligible to join the Sons of The American Legion if you are the male descendant (stepsons and adopted sons included) of a veteran who died subsequent to his or her honorable discharge from service in World War I, World War II, the Korean War, the Vietnam War, Lebanon, Grenada, Panama, or the Persian Gulf War (the same eligibility periods apply as above).

 If you need help obtaining the records to prove your eligibility visit The National Personnel Records Center, Military Personnel Records. It is the repository of millions of military personnel, health, and medical records of discharged and deceased veterans of all services during the 20th century. Information from the records is made available upon written request (with signature and date) to the extent allowed by law.
