"Secret operations are essential in war; upon them the army relies to make its every move"
About this Quote
The phrasing "essential" and "relies" strips strategy of bravado. An army "makes its every move" as if it were a single organism, but Sun Tzu is quietly pointing out how fragile that organism is. Without covert intelligence, deception, and secured communications, movement becomes guesswork, and guesswork becomes casualties. The subtext is managerial as much as martial: leadership is stewardship of asymmetry. You win by seeing more, being seen less, and shaping the opponent's perception until they help you lose.
Context matters: Sun Tzu is writing in a world of rival states where prolonged campaigns could bankrupt regimes and destabilize rulers. "Secret operations" are a cost-control measure as much as a tactical edge. Spies, scouts, false signals, divided loyalties - these are cheaper than sieges and safer than glory. It's also a warning about dependency: the moment an army treats secrecy as optional, it hands initiative to the enemy. In that sense, the quote isn't praising trickery; it's diagnosing reality.
