These non-lethal grenades are used to confuse, disorient, and even momentarily incapacitate a potential threat and can seriously degrade the combat effectiveness of affected personnel. As their name implies, flash bangs produce a blinding 1 million Candela flash and a deafening 170-180 decibel blast. When detonated, they remain intact to produce no fragmentation. The steel body tube has holes along the sides to allow the blast of light and sound to be emitted.
