Just as (Edward) Luttwak's logic of paradox permeates all levels and kinds of conflict, so Boyd's loop can apply to the operational, strategic, and political levels of war, as well as to tactics for aerial dogfights. Boyd's theory claims that the key to success in conflict is to operate inside the opponent's decision cycle. Advantages in observation and orientation enable a tempo in decisionmaking and execution that outpaces the ability of the foe to react effectively in time. This seemingly simple tactical formula was duly explained and copiously illustrated historically by Boyd in many briefings within the US defense community over the course of twenty years. The OODA loop may appear too humble to merit categorization as a grand theory, but that is what it is. It has an elegant simplicity, an extensive domain of applicability, and contains a high quality of insight about strategic essentials, such that its author well merits honourable mention as an outstanding general theorist of strategy.
