A fragmentation grenade (commonly known as a frag grenade) is an anti-personnel weapon that is designed to disperse shrapnel upon exploding. The body of the grenade is made of a hard metal casing that is filled with a high explosive material. When the grenade is detonated, the explosive force causes the casing to shatter into small, high-velocity fragments that are propelled outward in all directions. These fragments can cause serious injury or death
