What do you call the areas that concern a commander but are not necessarily under their direct influence?

The correct term for the areas that concern a commander but are not necessarily under their direct influence is the Area of Interest. This concept includes all the terrain and activities within the operational environment that could affect the mission, including areas beyond the immediate area of operations. Commanders must be aware of these areas to inform their decision-making and planning processes, even though they may not have control over them directly.

The Area of Influence, by contrast, refers specifically to the extent of a unit's operations and the area where it can directly impact the situation. The Operational Command Zone is not a standard term used in military doctrine, so it does not accurately represent the concept being examined. The Engagement Zone typically pertains to a specific area where engagements or combat may occur but does not encompass the broader scope of what commanders need to monitor as part of their Area of Interest. Thus, the Area of Interest effectively captures the needed situational awareness for a commander regarding influences that may impact their operation or mission outcomes.
