What is the burn time of a 40mm white star cluster?

The burn time of a 40mm white star cluster is indeed 7 seconds. This specific duration is crucial for tactical operations, as it provides a predictable window during which the cluster can illuminate an area or mark a target. The white star clusters are typically used in various military scenarios to signal to friendly forces, to create a visibility marker in low-light conditions, or to signal for support. Understanding the burn time helps infantry understand the operational capabilities and limitations of these munitions, allowing for better planning and coordination in the field. Knowledge of the exact burn time ensures that personnel can time their actions—such as movements or attacks—effectively in relation to the illumination or signal provided by the star cluster.
