"The phrase OODA loop refers to the decision cycle of observe, orient, decide, and act...
...As one of [OODA developer] Boyd's colleagues, Harry Hillaker, put it in "John Boyd,
USAF Retired, Father of the
F16":
The key is to obscure your intentions and make them unpredictable to your opponent while you simultaneously clarify his intentions. That is, operate at a faster tempo to generate rapidly changing conditions that inhibit your opponent from adapting or reacting to those changes and that suppress or destroy his awareness. Thus, a hodgepodge of confusion and disorder occur to cause him to over- or under-react to conditions or activities that appear to be uncertain, ambiguous, or incomprehensible."
