Which of the following is NOT a fire support coordination measure?

The Multi-Round Fire Area is considered a method of executing fire missions rather than a fire support coordination measure. It specifically refers to the ability to engage a target with multiple rounds of fire in a given area or at a specific target. In contrast, fire support coordination measures like the Fire Support Coordination Line, Kill Box, and Restrictive Fire Area are designed to manage and facilitate the use of different types of fire support in a coordinated manner to ensure safety and effectiveness.

The Fire Support Coordination Line acts as a boundary that separates areas where fire support can be freely used from those that require coordination with other forces. A Kill Box is a designated area that allows for the engagement of targets without additional clearance, typically used for air support. Conversely, a Restrictive Fire Area provides an area where fire can only be conducted under specific conditions or not at all, also intended to enhance safety and coordination. Understanding the distinctions between these terms is crucial in operational planning and execution.
