M84 Stun Grenade
The M84, also known as a flashbang or stun grenade, is the currently-issued stun grenade of the United States Army. Upon detonation, it emits an intensely loud "bang" of 170–180 decibels and a blinding flash of more than one million candela within five feet of initiation, sufficient to cause immediate flash blindness, deafness, tinnitus, and inner ear disturbance. Exposed personnel experience disorientation, confusion and loss of coordination and balance. While these effects are all intended to be temporary, there is risk of permanent injury or even death. Consequently, the M84 is classified as a Less-lethal weapon.
