The Handsid (Placed on the Ground by Foot Soldiers)
The initial sensor program was called PRACTICE NINE until 14 June 1967, ILLINOIS CITY until 15 July 1967, and DYE MARKER until 8 September 1967, when MUSCLE SHOALS was adopted to indicate the air-supported subsystem in eastern and central Laos. In June 1968, the program was renamed IGLOO WHITE and consisted of three components: (1) munitions and sensing devices which were placed across and along suspected routes of infiltration to detect and impede enemy foot or vehicular movement; (2) orbiting aircraft which received signals from these sensors, amplified them, and retransmitted them; and (3) an Infiltration Surveillance Center (ISC) which received the transmitted signals from the aircraft and analyzed them to produce reliable tactical information for planning and interdiction operations.
