Thank you, I enjoyed the above. Let me tell a true story about myself.
In 1949, after working almost 5 years as a cowboy on a large Idaho cattle ranch, having never lived in a town but lived approximately a year at a time on different farms after I lost my parents in as a boy. "Green as grass", I enlisted in the army.
After my physical, while the recruiter soldier was completing the paper work, I was asked for my Birth Certificate. I had never heard of a Birth Certificate and had no idea what he was talking about. He told me a Birth Certificate proved that I had been born. I told him where I had been born (on the reservation in Oklahoma), and told him I could not prove it, so he told me "We will let the Army handle that).
I was then asked, "What part of the Army did I want to join"? He named artillery, infantry, others, etc., none of which I knew anything about. I did mention that one farm where I had lived as a young boy was owned by a retired Army Sargent who had retired from the Cavalry. As a proud 19 year old cowboy, I told the recruiter, "The Cavalry, I can ride any damn horse the Army has".
The recruiter only said, "No you can't, The Army doesn't have any horses", as he signed my up for the Army Air Corps.
