What is the initial height of burst for all 120mm illumination rounds?

The initial height of burst for all 120mm illumination rounds is set at 500 meters. This height is critical as it ensures that the illumination effectively lights up the area and provides the necessary visibility during nighttime operations. By bursting at this altitude, the illumination round can provide a wide spread of light, allowing for greater situational awareness and effectiveness in target acquisition without significantly risking exposure to enemy fire.

Understanding this altitude is essential for Fire Support Teams to accurately plan and execute illumination missions, ensuring maximum effectiveness for ground operations and safety for friendly forces. The choice of 500 meters aligns with established field manuals and operational guidelines that dictate how these rounds are employed in various combat scenarios.
