What is the maximum number of critical friendly zones that can be entered into the radar?

The maximum number of critical friendly zones that can be entered into the radar system is nine. This limitation is established to effectively manage and delineate areas where friendly forces are located, ensuring that the radar can accurately identify and track incoming projectiles without mistaking them for friendly fire.

The critical friendly zones aid in preventing the engagement of friendly positions and are essential for the safety of troops on the ground. Having nine zones allows for sufficient coverage and flexibility when determining the safe areas for allied forces while maintaining the system's operational efficiency. The choice of nine is a balance between maximizing coverage and maintaining system performance, making it a well-considered design feature of the radar system.
