Kill zone
In military tactics, the kill zone, also known as killing zone, is an area entirely exposed to effective direct fire or accurately zeroed indirect fire, typically as an element of ambush within which an approaching enemy force is encircled/flanked, engaged and destroyed. The objective of the ambushing force is to seize the element of surprise to quickly kill or capture all hostile combatants inside the kill zone, and the ambushed soldiers (who may or may not be trapped) may respond by counterattacking and/or breaking out of the kill zone.
