pre-fragmented, high-explosive shell

Machine-translated from the Swedish article

Pre-fragmented high-explosive grenade, short PFHE (Swedish: kulspränggranat, short kulsgr), is a type of high-explosive grenade designed to primarily produce fragmentation effect, but also some blast effect. Like ordinary high-explosive grenades, they consist mainly of a steel grenade body fitted with an explosive charge, with the difference that the explosive charge is lined with metal balls (shot), for example of steel or tungsten alloy, packed along the inside of the grenade body, hence the name "ball-explosive grenade". On functioning, the detonation of the explosive charge causes the balls to be propelled at high speed in a lethal sphere beyond the range of the grenade body's fragments.
