Highest Level of Military War Fighting

The highest level of military war fighting is the strategic level. At that level, the military high command cooperates with civilian leaders to allocate resources for major long-range military campaigns. At the strategic level, army group operations are coordinated and planned. Air Force, Navy and land operations are planned concomitantly to achieve strategic level objectives.

“Sir Basil Liddell-Hart, one of the most competent western theoretical strategist of the twentieth century, defined military strategy as, "...the art of distributing and applying military means to fulfill the ends of policy..." Military strategy, originated in national policy aims and limitations, establishes general national objectives, assigns more specific objectives to individual theaters of war, and allocates resources and forces.
National strategists plan and direct the general course of the national military effort, allocate national resources and outline major campaigns. "Strategy might...be defined as a body of doctrine which both describes the conduct of conflict and prescribes the way this should be done..." "
