Therefore, a master of warfare subdues the enemy army without fighting, seizes enemy cities without storming, and overthrows enemy states without prolonged campaigns.
Strive for complete victory across the realm. Thus your troops suffer no exhaustion, and full gains are secured. This is the art of attacking by strategy.
Rules for military operations: If your force is ten times stronger than the enemy, surround them. If five times stronger, launch an assault. If twice as strong, divide their forces. When evenly matched, fight them. When outnumbered, defend. When far weaker, evade them.
A small force that stubbornly holds its ground will surely be captured by a powerful foe.
Note
A great military strategist and thinker in ancient China, who lived in the late Spring and Autumn Period. He authored The Art of War, the world’s earliest and most influential military classic. His strategic thoughts have been widely applied in military, politics and management worldwide.
Complete victory
The core idea of strategic attack. It pursues maximum benefits with minimum losses.
Troop deployment rules
Six tactical choices based on the comparison of military strength, a practical guide for ancient commanders.
Stubborn resistance of weak forces
A military warning. A small army insisting on reckless defense will end in failure.
Strategic attack
Using wisdom rather than brute force to defeat the enemy, the highest level of ancient military art.
The Strategy of Managing Choices: A Competitive Law
Sun Tzu’s philosophy is not merely about troop numbers, but about managing options and controlling the decision-making environment.
Overwhelming Advantage (10x): The Siege of Options
“If your force is ten times stronger than the enemy, surround them.”
The Principle: Total Denial.
Analysis: Surrounding the enemy is not about immediate annihilation; it is about enforcing “Complete Victory”. By encircling them, you cut off supply lines, block escapes, and isolate them diplomatically. You are removing every possible choice except surrender. This is using resource advantage to control the environment rather than impulsively consuming your strength in a head-on clash.
Strong Advantage (5x): The Creation of Dilemmas
“If five times stronger, launch an assault.”
The Principle: Forced Reaction.
Analysis: With 5x strength, you may not be able to block every exit, so you must create weaknesses. By attacking, you force the enemy to react to your moves. You use your surplus manpower to strike at their flanks or soft targets, making them defend everywhere. You manage their choices by making every defensive option look dangerous.
Moderate Advantage (2x): The Geometry of Deception
“If twice as strong, divide their forces.”
The Principle: Structural Superiority.
Analysis: This is the pivot point where quantity gives way to quality. You don’t have enough to overwhelm everywhere, so you can divide your forces, trick the enemy into spreading thin through feint, deception, etc. This allows you to create a local 2:1 advantage at the decisive point. You manage the battle space to make your limited advantage count where it matters.
Parity (1:1): The Battle of Wits
“When evenly matched, can fight them.”
The Principle: Organizational Edge.
Analysis: When numbers are equal, the physical variables are neutralized. The only advantage left is intellect, morale, and training. This is where “being able to fight” comes in. It means having the discipline and command structure to execute complex maneuvers that the enemy cannot. You manage the chaos of battle better than they do.
Disadvantage: The Strategy of Preservation
“When outnumbered, defend; when far weaker, evade.”
The Principle: Denying the Enemy Their Victory Conditions.
Outnumbered (Defend/Evade): When outmatched, the worst choice is to stand still. Many people mistakenly equate this with simply running away. In reality, the core essence of “evading” is to maintain mobility, preserve your strength, avoid the enemy’s sharp edge, and wait for variables to emerge. When you are at a disadvantage, the most crucial thing is not to stubbornly show off your strength, but to avoid falling into the decisive battle framework that your opponent has pre-set.
The Fatal Error: “Small Army’s Stubbornness”
Remember the famous General Li Ling？ He chose to stand firm/stubbornly with only 5,000 infantry resisting against 100,000 Huns. He played by the enemy’s rules. He allowed his options to be stripped away until there was only one choice left: capture or death.
Conclusion
Sun Tzu’s wisdom teaches us that strategy is the art of retaining your own freedom of action while systematically destroying the opponent’s. Whether you are a general on a battlefield or a competitor in business, the goal is never just to be stronger, but to be smarter about how you apply that strength to control the opponent’s choices.
故善用兵者，屈人之兵，而非戰也；拔人之城，而非攻也；毀人之國，而非久也。必以全爭于天下，故兵不頓，利可全，此謀攻之法也。故用兵之法，十則圍之，五則攻之，倍則分之，敵則能戰之，少則能守之，不若則能避之。故小敵之堅，大敵之擒也。
