A brief history of development Grenade has a long history and was first invented by China people. /kloc-black powder grenades appeared in Europe in the 0 th and 5 th centuries, which were mainly used for fortress defense and prisons. /kloc-in the middle of the 0/7th century, some European countries equipped their elite troops with grenades for field use, and called soldiers specially trained to use this ammunition grenadiers. In the19th century, with the development of guns and the reduction of offensive and defensive battles in castles, grenades were once given a cold shoulder.
In the Russo-Japanese War of 1904, grenades once again played a role in the battlefield. In World War I, grenades were widely used because of the rise of trenches. At that time, the typical grenades were German wooden handle grenades and British pineapple-shaped mills grenades. These grenades also laid the foundation for the development of grenades later.
During the Second World War, grenades were not only widely used, but also developed rapidly, and hollow-charged anti-tank grenades appeared. At that time, the development of grenades was mainly manifested in the following aspects: ① the firing mode was improved, and the directional collision and explosion mechanism appeared and began to be used in Grenade fuze; (2) The hollow charge structure is applied to the warhead of a grenade, which becomes an anti-tank grenade; (3) Various special grenades appear one after another, such as smoking, burning, tearing and stun grenades. ; (4) grenades began to use new materials.
In the mid-20th century, the development of hand grenades entered a new stage with the application of electronic fuze, semi-prefabrication of steel wire winding and full prefabrication of non-metallic materials such as steel balls, high-speed small fragments and plastics. American M26 Grenade, British L2A 1 Grenade and Belgian PRB423 Grenade are all typical products of this period.
