What is the primary purpose of a screen in military operations?

The primary purpose of a screen in military operations is to provide early warning to the protected force. A screening operation is designed to detect and report enemy movements and intentions while keeping the main forces informed and prepared for potential threats. This allows the protected unit to maintain an advantageous position and plan its next moves effectively, often facilitating a defensive posture or strategic withdrawal if necessary.

This approach enables the force to operate with a degree of security, as the screen acts as an advanced guard. It helps in gathering intelligence and can shape the battlefield by influencing enemy decisions without engaging in direct combat unless absolutely necessary. The focus of a screen operation is more on reconnaissance and timely information flow rather than direct confrontation or territorial seizure.
