Cluster munition
Explosive weapon with small submunitions
A cluster munition is a form of air-dropped or ground-launched explosive weapon that releases or ejects smaller submunitions. Most cluster munitions are designed to kill enemy personnel or destroy vehicles, but some are designed to destroy runways or electric power transmission lines. Because cluster bombs release many small bomblets over a wide area, they pose risks to civilians both during attacks and afterwards.
