Grapeshot used fewer but ...

A dual-purpose improved conventional munition (DPICM) is an artillery or surface-to-surface missile warhead designed to burst into submunitions at an optimum altitude and distance from the desired target for dense area coverage. The submunitions use both shaped charges for the anti-armor role, and fragmentation for the antipersonnel role, hence ...
