The M84 Stun Grenade, commonly known as a flashbang, is a non-lethal explosive device designed to temporarily disorient individuals. When detonated, it produces a blinding flash of light and a loud bang, which can impair vision and hearing for several seconds. This makes it useful in tactical situations, such as law enforcement operations or military engagements, where incapacitating a target without causing permanent harm is essential. Typically, the M84 is used by police and military units during hostage rescues or raids. Its design includes a cylindrical body filled with a pyrotechnic mixture, which creates the intense flash and sound. The grenade is thrown into a room or area to create confusion, allowing operators to gain the upper hand.
