“Though the enemy be stronger in number, we may prevent him from fighting. Scheme to discover his plans and the likelihood of their success.”

A bigger force can be made inert if you read its plan and remove the condition for its action.
Chapter 6 addresses the weaker side directly: though the enemy be stronger in number, we may prevent him from fighting — scheme to discover his plans and the likelihood of their success. Prevention, not confrontation. The verse reframes what a smaller force attacks: not the enemy’s army but the enemy’s plan, and specifically the one link in it that makes the numbers usable.
A small software vendor learns a giant is bundling a competing product free into a suite renewal. It cannot out-engineer or out-price that. It finds the link instead: the bundle requires a data-migration the giant’s own sales process makes painful. The vendor makes migration to itself one afternoon and migration to the bundle six weeks of forms — and the giant’s overwhelming numbers meet a conversion funnel it never planned to fight.
Preventing the fight is not appeasement or avoidance forever — the vendor fully intends to win the account. The verse’s schemes target the plan’s viability, never the person. And discovery comes first: without genuinely understanding the stronger side’s plan, "neutralization" is just hope with a vocabulary.
