Operational level of war
Between strategic and tactical warfare
In the field of military theory, the operational level of war (also called operational art, as derived from Russian: оперативное искусство, or operational warfare) represents the level of command that connects the details of tactics with the goals of strategy. In other words, it involves creating, through successful tactics in the theater of military operations, the conditions needed for strategic success. In U.S. Joint military doctrine, operational art is "the cognitive approach by commanders and staffs—supported by their skill, knowledge, experience, creativity, and judgment—to develop strategies, campaigns, and operations to organize and employ military forces by integrating ends, ways, and means".
