“Cluster munitions — or dual-purpose improved conventional munitions (DPICMs), as they’re officially known — are haphazard and notoriously faulty. Once fired, they release dozens of bomblets in the air that spread out and saturate football-field- or city-block-size areas. The direction or targets for those bomblets can’t be controlled, and they don’t always immediately explode, turning into de facto land mines. For those reasons, they are particularly dangerous to civilians during war, but also long after a conflict ends.”
