I believe that was for the special forces or Green Berets.
In May, 2016, I briefly played senior softball (I left for another team) with a black guy who claimed he was special forces in Vietnam and that he was training in Panama in November, 1969 when I arrived.
The guy was a bull shitter and the more he talked the more I began to see thru his lies. He was two years younger than me and at the time I arrived in Panama, I had just turned 19 in October so that meant that he would only have been 17 and impossible for him to be special forces. At best, he would only have completed basic training if he enlisted after grad. from HS in June of that year.
That July, we saw his picture on the local TV news. He had just been arrested for impersonating a federal officer. Turns out the guy had a criminal record and had done 3 years in prison and was released in Feb. of 2013 for the exact crime. The arrest in July 2016 netted him another 3 years in prison...................LOL!
There was a guy I knew in High School who was an incredible athlete. Gymnast, Fullback, you name it. He enlisted in the Army after High Scholl and came home for his first visit. He had previously stopped at Clothing Sales and bought a uniform he dressed up with everything he could buy. Sgt. Major stripes, Green Beret tab, master parachutist wings, you name it. Some Vets saw him wearing that around town and reported it. He spent 6 months in the stockade before his Dishonorable. Seriously changed his life. Knucklehead.
