What is included in the 'Coordination Instructions' sub-paragraph of an operation order?

The correct answer focuses on the synchronization and collaboration methods for units involved in an operation. This section of an operation order is crucial because it outlines how different units will coordinate their efforts to achieve operational objectives. Effective coordination instructions help ensure that all elements of the operation are working together smoothly, which can include specifying communication protocols, establishing common goals, and detailing what resources will be shared among units.

The emphasis on synchronization underscores the need for different components of an operation — whether they involve movement, logistics, or tactical maneuvers — to work in harmony. This collaboration is essential in complex operations where the timing and actions of multiple units can significantly impact the overall success of the mission.
