Define the sector of fire.

The concept of a sector of fire refers specifically to an area that is covered by a weapon's fire. This area indicates the specific zones that a weapon or a unit is responsible for engaging to ensure effective and coherent fire support during combat situations. It defines the range and lateral limits within which a weapon can effectively engage and fire upon targets, contributing to the overall tactical planning and execution of fire missions.

Understanding the sector of fire is crucial for coordinating engagements and preventing friendly fire incidents, as it helps define boundaries for the area in which units can operate without risking collision of fire. This clarity ensures that all personnel involved are aware of their responsibilities and the limits of their engagement zone, optimizing the effectiveness of their firepower. Other concepts such as target acquisition zones or weapon control zones serve different tactical purposes and do not specifically categorize the physical area managed by a weapon in terms of its fire capability.
