The Chinese military grenade, known as the Ff grenade, detonates in a circular area. The damage inflicted by the explosion is directly proportional to the distance from the blast center; the closer the target, the greater the damage. Conversely, if a target is outside the grenade's effective radius, it experiences no damage at all. This principle is consistent with how fragmentation grenades operate, dispersing lethal fragments within a defined radius while minimizing harm beyond that range
