General Charles C. Krulak served as the 31st Commandant of the Marine Corps (1995-1999). A Vietnam veteran and son of legendary Marine Victor "Brute" Krulak, he extended the Boyd-influenced maneuver warfare doctrine into the post-Cold War operational environment. Krulak's concepts of the "Three Block War" (Marines conducting humanitarian aid, peacekeeping, and high-intensity combat simultaneously within three city blocks) and the "Strategic Corporal" (junior Marines making decisions with strategic consequences) were natural extensions of Boyd's framework: decentralized decision-making, Auftragstaktik, the primacy of orientation over hierarchy. Krulak's tenure demonstrated that Boyd's influence on the Marine Corps was not a one-generation phenomenon but had become embedded in institutional culture.
