|---|
| Source measurement | — | Upon deflagration, it emits an intensely loud "bang" of 170–180 decibels and a blinding flash of 4.5 million candelas within 5 feet (1.5 meters) 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. Consequently, the M84 is classified as a less-lethal weapon .[source]M84 stun grenade · Design; only the objects and conditions stated in this passage |
