What is the approximate illumination duration of a 60mm illumination round?

The illumination duration of a 60mm illumination round is approximately 55 seconds. This characteristic is important for operational planning as it provides a relatively precise window of time during which troops can have visibility in a dark environment. The round is designed to emit bright light, aiding in target acquisition and increasing situational awareness for ground forces. Understanding the duration of illumination helps soldiers effectively coordinate movements and tactical decisions under the cover of darkness, maximizing the tactical advantage provided by the illumination round. The options provided reflect different durations, but 55 seconds is widely recognized as the optimal and most accurate estimate for this particular munition's performance.
