Other Applications
Though Igloo White's primary focus was monitoring traffic along the Ho Chi Minh Trail, the DCPG's mission had been expanded to include sensors for a "wide range of tactical applications," as well as, a "Ground Tactical System" in 1968. The Ground Tactical System was envisioned as a tool for ground commanders in defending fire bases and other secured areas against attack, and was eventually employed around Khe Sanh. It was also noted that the US border patrol was testing the sensor equipment as a method of protecting US continental borders. Sensor equipment was deployed by July 1969 in South Vietnam for the purposes of countering boobytrapping and mining teams. A total of 56 sensors were diverted to the problem as a test, with testimony that vehicle losses were reduced by 50 percent in the first month.
