What is the initial height of burst in meters for the M485A2 illumination round?

The initial height of burst for the M485A2 illumination round is 600 meters. This specific height is characteristic of the round's design, which is intended to provide optimal illumination for targeting purposes in a battlefield scenario. The round is engineered to burst at this height to maximize the effectiveness of the illumination, ensuring that the targeted area receives sufficient light to support visibility of the terrain and enemy positions.

In artillery and fire support operations, understanding the height of burst is crucial for effective coordination and safety, as it directly affects the illumination spread and bottom line effectiveness in completing the mission objectives.
