Fragmentation

Fragmentation grenades (defensive) are designed to disperse fragments on detonation, aimed to damage targets within a lethal radius. They are designed to be used from a position of cover against an open area, most often outside. They have an effective kill radius greater than the distance they can be thrown. The body is generally made of a hard synthetic material or steel and designed to rupture and fragment on detonation, sending out numerous fragments (shards and splinters) as fast-flying projectiles. In modern grenades, a pre-formed fragmentation matrix inside the grenade is commonly used, which may be spherical, cuboid, wire or notched wire.
