Abstract
In an infantry grenade (5) the fragmentation effect is enhanced in that a cup portion (7) of a ductile steel--which serves to receive an explosive charge (9)--has at its periphery in a substantially cylindrical longitudinal portion (25) a pre-notched fragmentation arrangement (28, 29) and in a rounded longitudinal portion (26) ball-type fragmentation portions (32). The entire fragmentation arrangement is enclosed by a plastic shell (17).
