Which of the following is NOT a movement formation?

The correct answer, indicating which option is not a movement formation, is Strong Point. The context of the question revolves around the identification of tactical movement formations used by units when maneuvering on the battlefield.

Wedge, Coil, and Herringbone are all recognized movement formations that facilitate specific operational objectives. The Wedge formation, for instance, is designed to provide a balance of firepower and maneuver while allowing units to maintain a cohesive structure. The Coil formation is used for encirclement operations, enabling units to effectively surround an enemy. The Herringbone formation allows for quick transitions into different operational actions, providing a versatile response during movement.

On the other hand, a Strong Point is a defensive position rather than a movement formation, designed to hold territory and provide a secured area from which units can engage in combat or provide support. It does not facilitate movement or maneuvering of units, which is the key characteristic of the other options. Thus, identifying Strong Point as the correct answer clarifies its role in a defensive strategy rather than a movement strategy.
