“The host thus forming a single united body, it is impossible either for the brave to advance alone, or for the cowardly to retreat alone.”

A truly unified force cannot have heroes or deserters act alone; the body moves as one.
Chapter 7 states the product of discipline: the host forming a single united body, it is impossible for the brave to advance alone, or for the cowardly to retreat alone. The sentence is usually read as suppression; it is equally a promise. A unified force makes individual heroics unnecessary and individual desertion impossible — the unit’s floor and ceiling collapse into one reliable movement.
A services firm’s star performers sell brilliantly and deliver erratically — each hero advancing alone, each client experience a coin flip on who staffed it. The turnaround is unglamorous: one delivery method, one quality bar, one schedule every team uses, stars included. Two founders quit ("process is killing excellence"). Three years later the firm’s reviews say "you always know what you’ll get" — and its enterprise pipeline, built on that reliability, dwarfs anything the heroes ever closed.
Unity is not the abolition of individual skill — the body is made of the brave and the cowardly alike, and it moves at the speed of its formation, not its slowest member’s fear. The misreading builds unity as conformity: everyone mediocre together. Sun Tzu’s united body channels individual talent through shared motion, which is why his armies drilled rather than standardized into sameness.
