Which area is defined as the measurement from the edge of a target or the aimpoint for a point target, used in delineating a hazard zone?

• A. Air Interdiction
• B. Collateral Hazard Area (CHA)
• C. No strike list (NSL)
• D. Dual use entity

Answer: (B)

The Collateral Hazard Area is the measurement from the edge of a target or the aimpoint for a point target, used to delineate a hazard zone. This boundary quantifies how far weapon effects (blast, fragmentation, debris) could spread beyond the target, helping planners assess risk to noncombatants and decide on munitions, trajectory, or safety radii. For a point target, the aimpoint becomes the center around which the hazard radius is defined. The other terms don’t describe this hazard-boundary concept: air interdiction is an operation type, a No Strike List is targets that must not be attacked, and a dual-use entity refers to a target with both civilian and military value, not the protective boundary around a target.
