A concussion grenade, also known as a flashbang, is a non-lethal explosive device designed to produce a loud noise and a bright flash of light. Its primary purpose is to disorient individuals in a specific area, making it useful in military and law enforcement operations. The device typically contains a small amount of explosive material that creates a shockwave and blinding light upon detonation. These grenades are often used in tactical situations, such as hostage rescues or building clearances, to gain a tactical advantage. While they are designed to minimize physical harm, they can still cause temporary hearing loss or other injuries if used too close to individuals.
