People sniffer

Personnel detectors used by the United States military during the Vietnam War

People sniffer was the field name for a series of U.S. Army issued "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.
