Which reference point is designated for fire control measures in the defensive tasking statement?

The correct reference point designated for fire control measures in the defensive tasking statement is the Target Reference Point. This point serves as a clearly defined marker used to facilitate communication and coordination of fire support among units during defensive operations. It allows for precise targeting and ensures that all personnel involved understand where the desired effects of fire will be applied.

The Target Reference Point is crucial because it reduces the potential for confusion during operations, where timely and accurate fire is vital for the success of the defensive strategy. By establishing a clear reference, units can effectively direct their firepower at specific locations to maximize effectiveness against enemy forces while minimizing the risk of friendly fire.

In contrast, the other options, while related to tactical operations, do not serve the same specific role in fire control measures as the Target Reference Point. Control Points are typically used for navigation and troop movement coordination, Engagement Zones are areas where units are prepared to engage the enemy, and Assault Lines delineate the boundaries for attacking forces rather than specifically addressing fire control.
