The key to winning a war is to act speedily. And the key to victory in warfare lies in seizing the initiative. Seizing the initiative means seizing the opportunity, because war situations change rapidly and opportunities to fight come and go instantly. So the army must act quickly to ensure the suddenness and success rate of combat operations. Otherwise, the initiative may easily fall into the enemy’s hands. If the war is prolonged, not only will there be unexpected consequences, but there will also be lowering of the army’s morale, leading to less effective combat and even falling into passivity (this is the same as the principle that “in war, seek quick victory, not prolongation”). This concept is also used to motivate people to do things decisively and quickly. It not only embodies the wisdom of Chinese military science, but also the philosophy that all procedures unfold according to time.
