Cluster munition is a type explosive weapon, which does not hit its ultimate target directly, but releases or ejects smaller submunitions in order to kill personnel or destroy vehicles. Single cluster munition can hit a wide area with its bomblets, thereby reducing the firepower needed to cover it. While militarily sensible cluster munition is also a matter of substantial humanitarian concern. A large number of submunitions may easily cause collateral damage especially when the weapon is used in densely populated areas. Furthermore, most submunitions are less then hundred percent reliable. Significant number of unexploded ordnance may be left in the affected area later causing death and injury to civilians. These humanitarian concerns led to Oslo process, which culminated in the Convention on Cluster Munitions that bans most cluster munitions.
