War gaming and military modeling have a well documented history covering over two centuries, a period that coincides with the inception and evolution of formal professional development for military officers. The term war game used here refers to “a warfare model or simulation that does not involve the operations of actual forces, in which the flow of events affects and is affected by decisions made during the course of those events by players representing opposing sides.”
