A hand grenade is a small explosive device designed to be thrown by hand. It typically consists of a metal casing filled with explosive material and a fuse. When the fuse is ignited, it detonates the explosive, creating a blast that can cause damage to nearby targets. Hand grenades are commonly used in military operations and can vary in type, including fragmentation, smoke, and stun grenades. The design of a hand grenade allows for easy handling and portability, making it a versatile tool in combat situations. Soldiers often carry them as part of their standard equipment, alongside other items like rifles and body armor. Proper training is essential for safe use, as mishandling can lead to accidental detonation.
