Provided are a method and system for eliminating the fighting strength of an opposing combatant using an electromagnetic wave the method comprises: a method for transmitting an electromagnetic wave of a specific frequency and strength so as to cause the brain of an opposing combatant to quickly enter a deep sleep pattern, thus eliminating the fighting strength of the opposing combatant a method for measuring, by means of transmitting and receiving electromagnetic waves, the degree to which the fighting strength of the opposing combatant is lost and an operation display control method for regulating the electromagnetic waves according to the measured degree to which the fighting strength of the opposing combatant has been lost, so as to ensure that the effective of eliminating the fighting strength of the opposing combatant is stable and meets standards, and providing relevant information to an operator. The system consists primarily of: a transmitting device for eliminating the fighting strength of an opposing combatant by means of transmitting an electromagnetic wave a monitoring device for measuring, by means of transmitting and receiving electromagnetic waves, the degree to which the fighting strength of the opposing combatant is lost and a operation display control method for regulating the transmission of the electromagnetic waves according to the measured degree to which the fighting strength of the opposing combatant has been lost, so as to ensure that the effective of eliminating the fighting strength of the opposing combatant is stable and meets standards, and providing relevant information to an operator.Linvention concerne un procédé et un système permettant déliminer la force de combat dun combattant adverse à laide dune onde électromagnétique le procédé comprend : un procédé pour transmettre une onde électromagnétique dune fréquence spécifique et dune force spécifique, de façon à amener le cerveau dun combattant adverse à entrer rapidement dans un mode
