Kill Box:
In weaponry, a kill box is a three-dimensional target area, defined to facilitate the integration of coordinated joint weapons fire. The space is defined by an area reference system, but could follow terrain features, be located by grid coordinates or a radius from a center point.

It is a joint forces coordination measure enabling air assets to engage surface targets without needing further coordination with commanders and without terminal attack control. Such a joint coordination measure can help commanders focus the effort of air and indirect fire assets, and also restrict the trajectories and effects of surface-to-surface fires. There may be no-fire areas (NFAs), restricted operations areas (ROAs), and airspace coordination areas (ACAs) included. No friendly ground forces should go into a kill box unless covered by a no-fire area.

A type of fire support coordinating measure (FSCM), a kill box is often defined by a grid reference system based on lines of latitude and longitude, superimposed upon a map of an area of operation. Each square of the grid may be sub-divided into smaller boxes, each of which may carry its own level of permission or restriction on the use of air-to-surface or surface-to-surface weapons.
