Judging from the other reviews, I wonder if anyone noticed that although the date of original publication has been removed, it is an FM published by HQs Dept of the Army, Washington 25, DC. That makes it 1963 or older, before zip codes were established. It is actually a wonderful historical document describing Special Forces organization, etc very early in the Vietnam War. For me, it brings back all kinds of memories of my youth. Just a great book!
