Attrition Warfare- Is a military strategy in which a belligerant side attempts to win a war by wearing down its enemy to the point of collapse, through continuous losses in personnel and material. The side with the most resources will most likely win the war.
During World War I the strategy of attrition was very widely used on the western front, most military theorists have suggested staying away from this type of warfare. It represents the opposite of the usual principles of war, where one attempts to achieve decisive victories through maneuvers, concentration of force, surprise, and so forth. On the other hand a side which perceives it to be at a marked disadvantage in maneuver warfare or unit tactics may deliberately seek out attrition warfare to neutralize its opponent's advantages.
