Upon detonation, a stun grenade produces a blinding flash of light and an extremely loud "bang".
They are often used in close-quarters combat, door breaching, and riot control, typically to stun enemies or distract them.
[5] Despite their less-lethal nature, stun grenades are still capable of causing harm, and can injure or kill when detonating in close proximity.
[6] Stun grenades are designed to produce a blinding flash of light of around 7 megacandela (Mcd) and an intensely loud "bang" of greater than 170 decibels (dB).
[9][10] The concussive blast has the ability to cause injuries, and the heat generated may ignite flammable materials.
