Definition/Scope: (FM 3-0) The method through which friendly forces accomplish their mission against enemy opposition. A defeat mechanism is described in terms of the physical or psychological effects it produces. Defeat mechanisms are not tactical missions; rather, they describe broad operational and tactical effects. Commanders must translate these effects into tactical tasks. Operational art formulates the most effective, efficient way to defeat enemy aims. Physical defeat deprives enemy forces of the ability to achieve those aims; psychological defeat deprives them of the will to do so.
