The period from 1973 to 1995 was one of the most challenging in the history of the United States Army. In an era of rapidly changing technology, sudden shifts in the threats facing the United States, and the need (particularly toward the end of the period) to operate on "short rations," Army leaders faced a number of complex and difficult decisions. Their ability to efficiently sort out the alternatives and find an effective solution was due in no small part to the support provided by Army operations research/systems analysis managers and analysts. This, the third and final volume of the history of operations research/systems analysis in the Army from 1942 to1995, covers the momentous events of the last quarter of the twentieth century and attempts to tell the story of when, where, and how the members of the Army analytical community supported Army decision makers and how the Army analytical community itself grew and evolved between 1973 and 1995.
