According to its original theorists, Shock and Awe renders an adversary unwilling to resist through overwhelming displays of power. Frequent comparisons are made by these theorists to the effect of the atomic bombings of Hiroshima and Nagasaki.
Shock and Awe is a military doctrine which advocates attempting to destroy an adversary's will to fight through spectacular displays of power. Its authors label it a subset of Rapid Dominance, a concept of defeating an adversary by swift action against all aspects of their ability to resist, rather than strictly military forces.
It is a product of the National Defense University of the United States, and has been notably applied in this country's 2003 invasion of Iraq.
Doctrine of Rapid Dominance
Rapid Dominance is defined by its authors, Harlan K. Ullman and James P. Wade, as attempting "to affect the will, perception, and understanding of the adversary to fit or respond to our strategic policy ends through imposing a regime of Shock and Awe." Further, Rapid Dominance will "impose this overwhelming level of Shock and Awe against an adversary on an immediate or sufficiently timely basis to paralyze its will to carry on . . . [to] seize control of the environment and paralyze or so overload an adversary’s perceptions and understanding of events that the enemy would be incapable of resistance at the tactical and strategic levels."Shock And Awe: Achieving Rapid Dominance (National Defense University, 1996), XXIV.
