A hand grenade is any small bomb that can be thrown by hand. A variety of types of hand grenades exist, with explosive grenades designed to detonate after impact or after a set amount of time the most commonly used in modern warfare.
Grenadiers were originally soldiers who specialized in throwing grenades.Anti-personnel fragmentation grenades are weapons that are designed to disperse lethal fragments upon detonation. The body is generally made of a hard synthetic material or steel, which will provide some fragmentation as shards and splinters, though in modern grenades a pre-formed fragmentation matrix is often used. The pre-formed fragmentation may be spherical, cuboid, wire or notched wire. Most AP grenades are designed to detonate either after a time delay or on impact.[2]
When the word grenade is used without specification, and context does not suggest otherwise, it is generally assumed to refer to a fragmentation grenade.
Anti-personnel fragmentation grenades can be divided into two main types, defensive and offensive, where the former are designed to be used from a position of cover, (e.g. in a slit trench or behind a suitable wall,) and have an effective radius greater than the distance it can be thrown, while the latter are for assaulting troops and have a smaller effective fragmentation radius.
Modern fragmentation grenades such as the United States M67 grenade have a wounding radius of 15 m (half that of older style grenades, which can still be encountered) and can be thrown about 40 m. Fragments may travel more than 200 m.[3]
