Defines theater, theater of operations

A theater of operations is an operational area defined by the geographic combatant commander for the conduct or support of specific military operations [jointchiefs2016dictionary].

The distinction between theater of operations and theater of war matters because it indicates who defines the area and for what scale of activity. In practice, theater boundaries are not only geographic; they are administrative and logistical: what can be sustained, what can be commanded, and what can be coordinated.
