Project AGILE

Project Agile covered a wide range of topics related to warfare under various conditions present in the Far East, from electronic surveillance, used to interdict Communist convoys in the Ho Chi Minh trail, to sociological research on troops likely to be subverted by Communist rebels. It was broken down into a number of subprojects.^[3][4][5]

Subprojects II and VIII were merged into Subproject I, and the resulting subproject covered weapons, individual equipment, and rations. Individual weapons included the M16 assault rifle, special purpose shotguns for use as insurgency weapons, flamethrowers, and rifle grenades. Crew served weapons included cupolas for armored personnel carriers, quad-mount machine guns, squeeze bore .50 to .30 in (12.7 to 7.6 mm) caliber guns, multiple shot grenade launchers, lightweight mortars, and the Stoner 63 weapons system.^[6]

Subproject III covered remote area mobility and logistics. Included were studies of air and land transport, amphibious and water transport, STOL aircraft, and remote airstrips.^[7]

Subproject IV covered communications systems. Both technical and procedural aspects of radio communications were studied, as well as power supplies and antennas.^[8]

Subproject V covered combat surveillance and target acquisition. Included were studies of airborne systems, such as infrared, radar, light amplification and spectral zone photography; surface use systems such as night vision, personal Doppler radar, target illumination, metal and cavity detectors; security and navigation systems.^[9]

Subproject VI covered "individual and special projects", which included use of herbicides (such as Agent Orange), psychological warfare, and medical research and equipment. The use of herbicides was largely inspired by the British use of 2,4-D and 2,4,5-T (a mixture designated "Agent Orange" by the U.S.) to destroy jungle-grown crops during the Malayan Emergency in the 1950s.^[10]

Part of Project Agile was Subproject VI and the "Outside the Contiguous US" (ONCUS) Defoliation Test Program was sponsored by the Advanced Research Projects Agency under Project Agile, ARPA Order 423.^[11] Conducted by the United States Army Biological Center which was based at Fort Detrick, Maryland, one test program was conducted in Thailand in 1964 and 1965 to determine the effectiveness of aerial applications of Purple, Orange, and other candidate chemical agents in defoliation of upland jungle vegetation representative of Southeast Asia.^[11] Data provided by these techniques were used in comparative evaluation of defoliant chemicals in relation to rate, volume, season of application, canopy penetration, and vegetation response.^[11]

There have been recurring allegations that similar tests have been conducted in Okinawa. Japan Times and Okinawa Times published accounts from an unnamed official claiming that "Pentagon had tested defoliants in the island’s northern jungles near Kunigami and Higashi villages." Other corroborating evidence is that in 1962, the U.S. Army counterinsurgency school in^{[clarification needed]} Vietnam moved to Okinawa. The USNS Schuyler Otis Bland (T-AK-277) was known to have brought highly classified "agriculture products" under armed guard to southeast Asia, Okinawa, and Panama.^[12] The ship's logbook was found by Michelle Gatz and shows the ship was carrying classified cargo that was offloaded under armed guard at White Beach a U.S. Navy port on Okinawa's east coast on April 25, 1962.^[12] After departing Okinawa in spring 1962, the Bland sailed to the Panama Canal Zone where, the Panamanian government asserts, the U.S. tested herbicides in the early 1960s.^[12] In June 2013, the US DoD rejected the allegations that Agent Orange being present on Okinawa, saying they had no factual basis.^[13] For example, according to the DoD report, the S.O. Bland was loaded with Agent Pink and Agent Purple, which it off loaded to Vietnam on 16–18 January 1962 before it stopped at Okinawa on 31 January 1962 on its way back.^[14]

The late author Sheldon H. Harris in his book Factories of Death: Japanese Biological Warfare, 1932—1945, and the American Cover-up wrote that field tests for wheat rust and rice blast were conducted throughout 1961 in Okinawa and at "several sites in the midwest and south", although these were probably part of Project 112. Harris attributes the rapid expansion of the US defoliant programs to these early successes.^[15]

Subproject VII covered technical planning and programming, including research into morbidity and casualties, environmental issues, and various tactical studies, both of Viet Cong operations, and other instances of asymmetric warfare, such as conflicts in Algeria and Latin America.^[16]
