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". It correlates political requirements with military power. Operational art is defined by its military-political scope, not by force size, scale of operations or degree of effort. Likewise, operational art provides theory and skills, and the operational level permits doctrinal structure and process. The operational level of war is concerned with four essential elements: time, space, means, and purpose. Through means such as directing troops and allocating (limited) resources (among others), operational art aims to achieve political goals by producing an optimal (or at least near-optimal) generation and application of military power. For example, proposals may be generated to identify where to build defensive structures, how many, what kind, and manned by how many troops; a proposal may be accepted, or reworked. During the 20th century, the nascent field of operations research flourished as a result of military efforts to improve logistics and decision-making. The operational level of war sits between tactics (which consists of organizing and employing fighting forces on or near the battlefield) and strategy (which involves aspects of long-term and high-level theatre operations, and government leadership). The Soviet Union was the first country to officially distinguish this third level of military thinking, which was introduced as part of the deep operation military theory that Soviet armed forces developed during the 1920s and 1930s and utilized during the Second World War.
Background During the 18th and early 19th centuries, the synonymous term grand tactics (or, less frequently, maneuver tactics) was often used to describe the manoeuvres of troops not tactically engaged. Subsequently, starting in the late 19th century and continuing throughout World War I and World War II, the term minor strategy was used by some military commentators. Confusion over terminology was exposed in professional military publications, that sought to identify "...slightly different shades of meaning, such as tactics, major tactics, minor tactics, grand strategy, major strategy, and minor strategy". The term operational art was not widely used in the United States or Britain before 1980–1981, when it became much discussed and started to enter military doctrines and officer combat training courses.
Application
Operational art comprises four essential elements: time, space, means and purpose. Each element is found in greater complexity at the operational level than at the tactical or strategic level. This is true partly because operational art must consider and incorporate more of the strategic and tactical levels than those levels must absorb from the operational level. Although much can be gained by examining the four elements independently, it is only when they are viewed together that operational art reveals its intricate fabric. The challenge of operational art is to establish a four-element equilibrium that permits the optimal generation and application of military power in achieving the political goal. Viewing time, space, means and purpose as a whole requires great skill in organizing, weighing and envisioning masses of complex, often contradictory factors. These factors often exist for extended periods, over great distances and with shifting mixes of players, systems and beliefs, pursuing political goals which may or may not be clear, cogent or settled. Compounding factors, such as the opponent's actions, create further ambiguity.
Mission analysis The operational-level strategist possesses numerous tools to frame and guide their thinking, but chief among these are mission analysis and end state. Mission analysis answers the question "What is to be accomplished?" Through mission analysis, the operational-level planner fuses political aims with military objectives. In so doing, the planner determines what application of military force will create military power to achieve the political purpose. Subordinate processes here include defining objectives and centers of gravity, but excessive dependence on analytical mechanisms can create false security. The final test rewards success, not the quality of the argument. Conversely, the planner cannot hope to "feel" a way to victory—complexity demands an integration of thought and effort.
End state End state answers the question "What will constitute success?" The campaign end state is not merely a desired status quo of the military goal. It also establishes a touchstone for the tactical, operational and strategic levels. The end state manifests the intended results of military power and exposes any limitations. Indeed, an achievable end state may require the employment of nonmilitary elements of national power. As such, it recognizes that military power alone may not be capable of attaining political success.
