Defeat the enemies strategy.
If you are far from the enemy, make him believe you are near.
And regulation entails organizational effectiveness, a chain of command, and a structure for logistical support.
Of old the expert in battle would first make himself invincible and then wait for his enemy to expose his vulnerability.
So the important thing in a military operation is victory, not persistence.
If we wish to fight, the enemy can be forced to an engagement even though he be sheltered behind a high rampart and a deep ditch. All we need do is attack some other place that he will be obliged to relieve.
