What is economy of force?

The concept of "economy of force" in military strategy involves the efficient use and distribution of military assets to achieve the maximum possible effect. Jocko Willink explains that economy of force requires using sufficient force at various points to enable the concentration of maximum force at the decisive point and time. It is about applying the necessary force to accomplish an objective, not merely using minimal force. This principle ensures that forces are not wasted or overly concentrated where they are not needed, allowing for a focus on critical areas of a battle or campaign 1.
