A draft chapter of a proposed book on military planning in an uncertain world. The levels of war gaming discussed are (1) the informal game, an attempt to determine the enemy's reactions; (2) rule games, designed to abstract from the real world a fairly definite set of rules which all players must observe; (3) the formal minimum rule game which investigates the sensible rules of play; and (4) realistic war games where maneuvers and training exercises are tested in a realistic environment or in realistic contexts.
