摘要:This article addresses what has changed in the conduct of war, especially with respect to the way intermediate-level leaders— lieutenants to colonels and some noncommissioned officers— experience, talk about, and conduct their business within the context of the operational level of war. In modern military parlance, the United States and many militaries around the world divide warfare into three levels: strategic, operational, and tactical. Most people conceive of the individual military member as simply a tactical entity—someone who engages the enemy in close physical proximity, conducting maneuvers within a specific domain such as the battlefield, sea, or air. This article, however, looks at the art of war from the perspective of the operational level: a practice, an outlook, and a set of organizing and planning constructs situated between tactics and strategy.
