Attrition warfare, also known as "war of attrition", is a military strategy that involves wearing down an enemy through continuous losses in men and material, rather than defeating them directly. Synonyms for this term include "war of erosion", "war of exhaustion" or "war of attrition-by-exhaustion". Other similar concepts could include "sapping", which is a process of weakening an enemy by slowly but steadily draining their resources, or "siege warfare", which involves surrounding and cutting off an enemy's supplies until they are forced to surrender. Ultimately, these strategies are aimed at outlasting and ultimately defeating an enemy through persistence and strategic maneuvers.
