Project Dye Marker
Project Dye Marker was a cover name for a strong point/obstacle component of the electronic anti-infiltration barrier system in South Vietnam known as ''McNamara Line'' during the Vietnam War, which aimed to create an alternative to the US bombing of North Vietnam. The fortifications were partially constructed by the American forces in 1967-1968 along the eastern portion of the demilitarized zone. An effective anti-infiltration barrier, running across South Vietnam deep into Laos, was a grand vision of the US Secretary of Defence Robert McNamara, who feared that escalation of bombing can bring greater Chinese involvement,〔Memorundum: Evaluation of Alternative Programs for Bombing North Vietnam. Central Intelligence Agency, 1June 1967. (PDF )〕 and a vital component of his operational strategy. It was an enormous multimillion project, which was nicknamed in the media as the Great Wall of Vietnam,〔(The Great Wall of Vietnam ), ''Science Digest'', April 1968.〕 McNamara's Wall, McNamara Barrier,〔McNamara Barrier May Be Expanded. ''The Boston Globe'', Oct 14, 1968, p. 7.〕 Electric Fence, and Alarm Belt.〔
==History==
The ''Dye Marker'' defensive line project, previously called ''Practice Nine'' and ''Illinois City'', stretched along the demilitarized zone starting from the South China Sea, and had a total length of 76 kilometers (47 miles). Some parts of the defensive line were manned and equipped with the bunkers, outposts, reinforcing and fire support bases, surrounded by concertina wire. Other segments were under constant radar, motion and acoustic surveillance, and secured by trip wires, mine fields, and barbed-wire entanglements. The airborne receiving equipment carried by EC-121R's relayed the signals and triggered artillery and bombers responses.〔Sikora, Jack, and Larry Westin.

The plans that ware leaked to the media called for an inexpensive barbed wire fence with watch towers, and they were presented to the public as a trivial measure, while the electronic part was highly classified. In reality, the strong-point part of the anti-infiltration system in Quang Tri Province, Vietnam was reinforced with electronic sensors and gravel mines to stop the flow of North Vietnamese troops and supplies through the demilitarized zone during the decisive years of the Vietnam War.〔("Nation: Alarm Belt" ), Time Magazine, Friday, September 15, 1967.〕 Construction was announced on September 7, 1967, and was carried by the 3rd Marine Division. First, the 11th Engineers started to work on bulldozing the so-called ''Trace'', a path 600 meter wide and 11 kilometers long that was stripped of trees, brush and villages if needed. The backbone of the strong-point system were fortified bases ''Alpha 2'' at Gio Linh on the east, ''Alpha 4'' at Con Thien on the west, and ''Alpha 3'' in between.〔(Alpha Bases Along the DMZ ) Companion website to DMZ DIARY by Jeff Kelly〕 7,578 American marines have been deployed in support of Dye Marker strong point/obstacle system by 1 November 1967. In addition, 4,080 American troops have been involved in the air-supported anti-infiltration part of Dye Marker.〔
