There are a number of different ways this is to be accomplished, but generally they all rely on building up a false image of the defender's actions, deliberately presenting forces in locations that appear to suggest a line of action and then attacking from different locations entirely. Key to the entire concept is rapid movement. The goal is to think not in terms of "layers of defence" as in traditional counter-armor doctrine, but in terms of "channels" that the enemy will be forced into. Once channelized, any commander in the field will have the capability to launch flanking attacks at any point on his own initiative. Such attacks would appear random to the enemy, and would be considered uncoordinated under traditional planning, but would in fact all be carrying out the primary goal of the tactic, causing confusion. In the wrap-up section, Boyd concludes that the art of success is to "[a]ppear to be an unsolvable cryptogram while operating in a directed way" while also attempting to convince potential enemies and neutrals of the superiority of the commander so that they "are empathetic towards our success." In January 1980 Boyd gave his briefing "Patterns of Conflict" at the Marine Corps Amphibious Warfare School. This led to the instructor at the time, Michael Wyly, and Boyd changing the curriculum, with the blessing of General Trainor. Trainor later asked Wyly to write a new tactics manual for the Marines. John Schmitt, guided by General Alfred M. Gray, Jr. wrote "Warfighting", collaborating with John Boyd during the process. Wyly, Lind, and a few other junior officers are credited with developing concepts for what would become the Marine model of maneuver warfare. In 1981 Boyd presented "Patterns" to Richard Cheney, then a member of the United States House of Representatives. By 1990 Boyd had moved to Florida because of declining health, but Cheney (then the Secretary of Defense in the George H. W. Bush administration) called him back to work on the plans for Operation Desert Storm. Boyd had substantial influence on the ultimate "left hook" design of the plan.
