Patterns of Conflict
1976 American military lecture by John Boyd

Patterns of Conflict was a presentation by Colonel John Boyd outlining his theories on modern combat and how the key to success was to upset the enemy's "observation-orientation-decision-action time cycle or loop", or OODA loop. Patterns developed the idea of a "counter-blitz", a blitzkrieg in reverse, with numerous attacks followed by withdrawals to the rear. The aim was to confuse the enemy by presenting no apparent strategy, reveal the enemy's intentions through the strength of the response, and present a misleading picture of the defender's own actions in order to disrupt the attacker's future plan of action.
First presented in 1976, Patterns grew enormously popular through the 1970s, and was re-presented on many occasions, including a personal presentation to Dick Cheney in 1981. A 1980 presentation to the US Marine Corps led to the development of an entirely new doctrinal system. Boyd's ideas also became the basis for the AirLand Battle, the US Army's European warfighting doctrine from 1982 into the late 1990s. Patterns has been widely regarded as one of the most influential works of warfighting theory of all time and has been compared to the writings of Sun Tsu. Based on Patterns and the work that followed, Boyd has been called "America's greatest military theorist".

Why this record matters
“Patterns of Conflict” is worth following because a concise public description often conceals a longer documentary argument. Here, Patterns, Conflict and American provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 5, 2026. The linked authority identifier is Q7148409. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1976, 1981, 1980 and 1982.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
