Any veteran who served on active duty during the Korean and Vietnam Wars quickly learned that the U.S. military had its own unique language. It was a combination of acronyms, technical jargon and a considerable sprinkling of vulgarities. "e;Nice Talk, GI,"e; is a compilation of terminology used, overheard, or encountered by the author during his service with the U.S. Army from 1969 to 1971. An invaluable resource was the author's own "e;Soldier Notebooks,"e; kept during BCT and AIT. Also, while stationed in Korea, he served with a number of Vietnam War Veterans, and learned a significant amount of technology from them. An invaluable source was provided by access to Pacific Stars & Stripes newspaper from the era. While the work does not claim to be definitive, it is representative of terminology used by military personnel between 1950 and 1975.
