The OODA Loop was named by Air Force pilot John Boyd to describe the psychological process leading up to an action. The power of this concept is to identify bottlenecks in response times during violent encounters so as to speed up reaction times. OODA loop can also be used to gain a tactical advantage over an enemy by causing bottlenecks in their decision making processes. OODA stands for OBSERVE, ORIENT, DECIDE, ACT and has become the basis for law enforcement training models. In this video, Instructor John Lovell teaches 1 Man Room Clearing students Boyd's OODA loop using visual examples as well as fun pop-culture examples like Sherlock Holmes.
