What defines an area where fires are entirely prohibited?

An area where fires are entirely prohibited is defined as a No Fire Area. This designation signifies that all types of fires, including indirect fire and air-to-ground munitions, are strictly forbidden within the specified boundaries. The purpose of establishing a No Fire Area is often to protect civilians, preserve critical infrastructure, or ensure safety during specific operations or events.

The other options have distinct definitions: a Restrictive Fire Area allows for fire under certain conditions but imposes limitations to minimize collateral damage; a Free Fire Area permits engagement of targets without prior clearance; and a Kill Box is a restricted area where specific combat operations can occur, typically allowing for certain types of fires but not necessarily prohibiting them entirely. Understanding these distinctions is crucial for effective fire support operations and ensuring compliance with the rules of engagement.
