This is kind of a stretch but I have a friend who found some information about his grandfather in an old diary and it peaked my interest.
He was stationed at Takhli in 1969 and was of Native American descent. Really the only information I have is that he was a Ute from Colorado with the last name Smith.
I don't know if there were a lot of Native American soldiers in Takhli so that is really the best I can do to narrow it down.
