Jan Fischer, American Soldier In His Military Life

Military strategy is the management of forces in wars and military campaigns by a commander-in-chief employing large military forces either national and allied as a whole, or the component elements of armies, navies and air forces such as army groups, fleets and large numbers of aircraft. Military strategy is a long-term projection of belligerents' policy with a broad view of outcome implications, including outside the concerns of military command. Military strategy is more concerned with the supply of war and planning, then management of field forces and combat between them. The scope of Strategic military planning can span weeks, but is more often months or even years.
• Operational victory
Operational mobility is, within warfare and military doctrine, the level of command which coordinates the minute details of tactics with the overarching goals of strategy. A common synonym is operational art.
The operational level is at a scale bigger than one where line of sight and the time of day are important, and smaller than the strategic level, where production and politics are considerations. Formations are of the operational level if they are able to conduct operations on their own, and are of sufficient size to be directly handled or have a significant impact at the strategic level. This concept was pioneered by the German army prior to and during the Second World War. At this level planning and duration of activities takes from one week to a month, and are executed by Field Armies and Army Corps and their naval and air equivalents.
