NICO BTV-1 flash-bang grenade

The NICO BTV-1 flash-bang grenade is a flash-bang grenade used in the United States.

It is designed to deny access into/out of an area to individuals, move individuals through an area, and suppress individuals.

It is a hand-thrown interim replacement for the MK-141 flash-bang grenade based on an urgent needs statement. Improvements prevent serious injury to personnel in the event of premature detonation of the grenade, provide 3–5 seconds of flash blindness, a lower pressure to reduce blast injury risk, and hand-safe capability with metal body and top and bottom venting.
