title: Combat science: the emergence of Operational Research in World War II.
abstract: World War II became known as the "wizard war" because the cycles of developing countermeasures and counter-countermeasures to the weapons deployed by all sides drove rapid technological change. However, technological innovation was not the only contribution scientists made to the war effort. Through Operational Research (OR)--the scientific scrutiny of new weapons, their deployment and relative efficiency--scientists also influenced how warfare itself was conducted. This new scientific field emerged in the UK, where it helped to tighten the defense against the Luftwaffe. It quickly spread to other aspects of the military machine, improving both antisubmarine campaigns and bombing strategy. But although this analytical approach to warfare offered military commanders a factual basis on which to base difficult decisions and deal with tactical and strategic uncertainty, it was not without controversy. Indeed, several recommendations that came out of OR sparked disputes over the allocation of resources and strategic priorities.
