The “transient” is the change between maneuvers. In Boyd’s concept, the ideal asymmetric fast transient is an abrupt, unexpected, jerky, disorienting change that causes at least a hesitation and preferably plants the seeds of panic in the other side. It’s a “What-the f___k!” change in circumstances, and in the interval when the opponent is trying to comprehend what the f___k is, Boyd would strike.
