In a war of attrition, countries ramp up their production of arms. In addition, countries bomb the opposition's war production facilities in order to stop the enemy from resupplying.

Furthermore, various means are used to harm an enemy's economy such as economic sanctions. | In a war of attrition, countries ramp up their production of arms.
