Why John Boyd Still Matters

John Boyd’s intellectual framework for competition and conflict fundamentally reshaped the United States Marine Corps’ warfighting philosophy. As a fighter pilot, Boyd developed the energy-maneuverability theory to gain tactical advantages through superior agility rather than raw power, eventually distilling these concepts into the OODA loop—a decision-making cycle emphasizing relative tempo over absolute speed. Ian Brown, author of *A New Conception of War*, explains how Boyd’s focus on breaking an adversary into non-cooperative centers of gravity provided the Marine Corps with a viable strategy for success despite limited resources. By targeting an opponent’s mental and moral cohesion rather than just physical assets, this maneuverist approach remains highly relevant in modern warfare, where narrative, information, and precision strike complexes serve as critical vectors for demoralizing and unhinging adversaries.
