Area or place where important military events occur or are progressing

In warfare, a theater or theatre is an area in which important military events occur or are in progress. A theater can include the entirety of the airspace, land, and sea area that is—or that may potentially become—involved in war operations.

Theater of operations (TO) is a sub area within a theater of war. The boundary of a TO is defined by the commander who is orchestrating or providing support for specific combat operations within the TO. Theater of operations is divided into strategic directions or military regions depending on whether it is a war or peacetime. Unified combatant commands of the Department of Defense (United States) have responsibility for military activities (combat and non combat) within their area of responsibility.

The term theater of operations was defined in the American field manuals as the land and sea areas to be invaded or defended, including areas necessary for administrative activities incident to the military operations (chart 12). In accordance with the experience of World War I, it was usually conceived of as a large land mass over which continuous operations would take place and was divided into two chief areas—the combat zone, or the area of active fighting, and the communications zone, or area required for administration of the theater. As the armies advanced, both these zones and the areas into which they were divided would shift forward to new geographic areas of control.
