What type of maneuver control measure is used for the coordination of military operations?

The phase line is used as a maneuver control measure to coordinate military operations effectively. It serves as a reference point on the battlefield, indicating a predefined line that units must reach or cross at a certain time. This helps in synchronizing movement, ensuring that different elements of an operation are progressing in a coordinated manner. By utilizing phase lines, commanders can manage their forces' timing and control their movements against the enemy, while also facilitating communication and situational awareness among units.

Phase lines are crucial for setting operational tempo and maintaining a clear understanding of the battlefield dynamics, allowing for timely adjustments in tactics and strategies based on real-time conditions. They also play a vital role in mission planning and execution, enabling leaders to monitor progress and allocate resources effectively during engagements. This is why the phase line is the chosen answer for coordinating military operations within the context of maneuver control measures.
