What does the Purple Kill Box establish for operations?

• A. It designates a no-fly zone for all aircraft.
• B. It sets a maximum range for missiles.
• C. It confines air operations to a single altitude band.
• D. It enables joint fires by establishing an altitude floor for air-to-surface and surface-to-surface operations.

Answer: (D)

Purple Kill Box is a joint airspace coordination measure that enables fires by defining a three-dimensional area with a specified minimum altitude. Within that space, air-to-surface and surface-to-surface engagements can be conducted without additional coordination, as long as aircraft remain above the floor. This speeds target prosecution and ensures deconfliction with other airspace users. It is not a blanket no-fly zone applying to all aircraft, it does not set a maximum missile range, and it does not simply confine operations to a single altitude band; the defining feature is the altitude floor that unlocks joint fires inside the box.
