Answer:
A grenade is an explosive weapon typically thrown by hand (also called by the retronym hand grenade), but can also refer to a shell (explosive projectile) shot out by a rifle (as a rifle grenade) or a grenade launcher. A modern hand grenade generally consists of an explosive charge ("filler"), a detonator mechanism, an internal striker to trigger the detonator, and a safety lever secured by a linchpin. The user pulls the safety pin before throwing, and once thrown the safety lever gets released, allowing the striker to trigger a primer that ignites a fuze (sometimes called the delay element), which burns down to the detonator and explodes the main charge

A stun grenade, also known as a flash grenade, flashbang, thunderflash or sound bomb,is a less-lethal explosive device used to temporarily disorient an enemy's senses. It is designed to produce a blinding flash of light of around 7 megacandela (Mcd) and an intensely loud "bang" of greater than 170 decibels (dB). It was first used by the British Army's Special Air Service in the late 1970s.
The flash temporarily activates all photoreceptor cells in the eye, blinding it for approximately five seconds. Afterward, victims perceive an afterimage which impairs their vision. The sheer volume of the detonation also causes temporary deafness in the victim and also disturbs the fluid in the ear, causing a loss of balance.
