Wartime tactic is a term used to describe a strategy employed during a conflict. A common example of this is SIEGE, which is a tactic used to force an enemy to surrender by surrounding them and cutting off their supplies. SIEGE involves the use of military force to surround a city or fortress and prevent supplies from entering or leaving. This can be done through the use of blockades, bombardment, or other means. The goal of a SIEGE is to weaken the enemy's morale and force them to surrender.
