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 indeed 600 meters. This specific height is critical for maximizing the effectiveness of the illumination while supporting ground operations. When the round is fired and reaches this altitude, it emits a strong light to illuminate the battlefield, which is essential for troops to identify enemy positions or navigate in low-visibility conditions.

Understanding the initial height of burst is critical for Fire Support Teams (FIST) because it directly impacts the planning and coordination of fire missions. The height allows for optimal dispersion of light and ensures that the illumination duration is maximized, which enhances situational awareness for ground forces. Recognizing this helps in making informed decisions on mission planning and execution during operations involving illumination rounds.
