Background

The grenade is a kind of super-caliber ammunition launched by gun and bullet or blank ammunition, and its initial speed is obtained by the action of gunpowder gas in gun and kinetic energy of bullet, and is mainly used for dealing with raw target, armored target and non-armored target. Grenades are substantially similar in construction to fin stabilized shells, except that a tailpipe assembly is provided for firing, with a buffer and bullet collector being incorporated into the tailpipe. Before shooting, the grenade is sleeved on the gun barrel, and the bullet impacts the collector during firing, and a certain initial speed is obtained under the action of gunpowder gas.

The riot grenade is mainly used for temporarily disabling group or individual targets without generating permanent disability, and belongs to the category of non-lethal ammunition. Currently, non-lethal ammunition plays an important role in the tasks of army, armed police, public security, anti-terrorism, sudden handling, maintenance, maritime maintenance and the like, but the problems of shorter range, lower precision, single function and the like generally exist, and for the hand-throwing antiriot ammunition with shorter range, in order to achieve the expected tactical effect, a thrower has to approach criminal suspects or violent harassment crowds, so that the thrower is exposed to the striking range of the other party (such as attack of bricks, stones and glass bottles). The explosion proof ammunition of the gun is used for avoiding explosion accidents, is usually combustion ammunition, cannot form larger deterrence for long-distance targets, but explosion type non-lethal ammunition with larger deterrence, such as detonation ammunition and explosion accelerating ammunition, shortens throwing distance greatly by adopting a hand throwing mode, and has heavy potential safety hazards such as hand explosion and the like, so that the non-lethal ammunition cannot effectively cope with increasingly complex and variable anti-terrorism and stabile situations.
