Defeat (E). 
======. 
1. Defeat is a tactical mission task that occurs when an enemy force has temporarily or permanently lost the physical means or the will to fight. 
2. The defeated force's commander is unwilling or unable to pursue his adopted course of action, thereby yielding to the friendly commander's will and can no longer interfere to a significant degree with the actions of friendly forces. 
3. Defeat can result from the use of force or the threat of its use. 
 
4. A commander can generate different effects against an enemy to defeat him: 
     a. Physical.  The enemy loses the physical means to continue fighting. 
                  He no longer has the personnel, weapon systems, equipment, or supplies to                    
                  carry out his assigned mission. 
b. Psychological.  The enemy loses the will to fight.  He becomes mentally exhausted,  
    and his morale is so low that he can no longer continue to carry out his assigned   
    mission.
