What is a key consideration when planning a screen operation?

When planning a screen operation, a key consideration is the need for depth. Depth in a screen operation allows for a more effective and resilient defense against enemy observation and potential engagements. It enables the cavalry forces to create barriers to protect the main body while also providing space to maneuver and respond to enemy actions. This depth facilitates the screening unit's ability to gather intelligence and conduct reconnaissance over a wider area, ensuring better coverage and the capacity to react to threats.

Depth also allows for more flexibility in positioning forces to ensure that the screen remains effective, even if parts of it come under pressure. This strategic aspect is crucial in maintaining an effective screen that informs and protects the main elements of the force, offering time and space to react to enemy movements.
