grenade

A hand grenade is a small explosive device designed to be thrown by hand. It typically has a thin metal case filled with explosive material, a detonator, and a fuse or pin that must be pulled or released in order to activate the weapon. Hand grenades have been used in warfare since the 15th century and are still used by military forces around the world today. They are designed to inflict damage and injury within a limited radius, often used for clearing out enemy positions, destroying fortifications, or disabling vehicles.
