Flash Bang

The flash bang is a weapon in the Fallout: New Vegas add-on Lonesome Road.

Characteristics
The flash bang is a different type of grenade that deals fatigue damage. In addition, they also reduce enemy weapon skills and have a chance to frenzy tunnelers and/or render them unconscious. Upon detonation, the grenade releases a large explosion of blue colored energy.

Getting caught in a flash bang's radius yourself causes your screen to either blur or turn completely white (depending on how close you were to the blast). In addition your hearing is severely affected. In other words you are completely combat-ineffective until the effects wear off.

Locations

 * Found on the dead bodies of a dead NCR trooper when first entering the Collapsed Overpass Tunnel.
 * Can be found on marked hunters and marked scouts in varying amounts (1-3+).
 * Can be found on the occasional dead NCR trooper or NCR Ranger, typically in caves or other dark areas.

Background
A flashbang is a non-lethal weapon. The first devices like this were created in the 1960s at the order of the British Special Air Service as an incapacitant. These grenades are designed to temporarily neutralize the combat effectiveness of enemies by disorienting their senses. The flash of light momentarily activates all light sensitive cells in the eye, making vision impossible for approximately five seconds until the eye restores itself to its normal, unstimulated state. The extremely loud blast produced by the grenade adds to its incapacitating properties by disturbing the fluid in the ear.

When detonated, the fuse/grenade body assembly remains intact. The body is a tube with holes along the sides that emit the light and sound of the explosion. This avoids shrapnel injury, but can still burn. The concussive blast of the detonation can injure and the heat created can ignite flammable materials such as fuel. The filler consists of about 4.5 grams of a pyrotechnic metal-oxidant mix of magnesium or aluminium and an oxidizer such as ammonium perchlorate or potassium perchlorate.
