Approximately two linear feet of mostly personnel and organizational records document the activities of the Army Concept Team in Vietnam (ACTIV) primarily from 1969-1971 and its research laboratory in Aberdeen, Maryland known as the Land Warfare Laboratory (LWL) from 1961-1974. This was the army's quick-reaction research and development group. The LWL records are the only copy remaining of the complete work-product of LWL from its inception in about 1961 through its closure in 1974. The legacy of LWL/ACTIV is still apparent today. A very small group was responsible for the initial ^D'invention^D>' of bomb-sniffing dogs, sophisticated electronics, simple chemical devices like light-sticks, and a host of other quick solutions to field problems. They were purposely exempted from standard R & D research rules, and were, therefore, unencumbered by bureaucracy, budget constraints, rigid organizational turf battles, and procurement policies. LWL/ACTIV was staffed by no more than 144 individuals who were brilliant scientists, and support personnel such as metallurgists, model makers, and researchers among others.
