What is the initial height of burst for all 105mm illumination rounds?

The initial height of burst for all 105mm illumination rounds is 750 meters. This height is significant as it is designed to optimize the effectiveness of the illumination provided by the round, ensuring that the area being targeted is adequately lit for observation and targeting purposes. The 750-meter height allows for a broad dispersion of light, illuminating a wider area on the ground while minimizing the risk of the illumination being obscured by terrain or environmental factors.

Choosing this height takes into consideration various factors including the operational requirements of the mission, the need for visibility, and the type of environment in which the illumination will be used. By deploying the illumination round to this specific height, the fire support team can ensure maximum effectiveness and utility during night operations or low visibility conditions.
