Fragmentation grenades are explosive devices designed to disperse shrapnel upon detonation. They typically contain a metal casing that breaks apart, sending sharp fragments in all directions. This makes them effective for inflicting damage over a wide area, particularly against enemy personnel. These grenades are commonly used by military forces and are often thrown by hand or launched from a grenade launcher. The design allows for a quick and powerful attack, making them a standard tool in combat situations. Safety mechanisms, such as pins and safety levers, are included to prevent accidental detonation before use.
