People Sniffer (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. People sniffer was the field name for a series of U.S. Army personnel detectors used during the Vietnam War. The purpose was to detect enemy soldiers in hidden positions, which were often employed in the jungle combat conditions of Vietnam. The U.S. military used two different versions of the people sniffer, one backpack version and one helicopter-mounted version.The detection method used by people sniffers depended on effluents unique to human beings; such as those found in urine and sweat. The technology was developed by General Electric for the Army's Chemical Corps. Sweat, being partially composed of ammonia, when combined with hydrochloric acid produces ammonium chloride. Chemical officers planned the detection missions, later known as Operation Snoopy, while individual Chemical Corps soldiers learned how to use the detector equipment and conduct detection operations.
