Flash-Ball is a registered trademark for a less-lethal hand-held projectile launcher developed by French hunting firearms manufacturer Verney-Carron.

Flash-Ball is intended to be used by riot police as an alternative to lethal firearms, bean bag rounds and plastic bullets.

According to the manufacturer's own publicity, the Flash-Ball's standard round has the stopping power of a 9 mm calibre handgun but considerably less kinetic energy per square centimetre, making it unlikely to penetrate the body of a normally clothed person even at ranges down to 5 metres (5.5 yd).

Various human rights groups have expressed fears that the widespread deployment of such weapons could result in police being less likely to apply de-escalation tactics when dealing with potentially dangerous situations.

[2] Numerous eye losses, comas, and brain traumas[3] as well as major bone breakages[4][5] and two deaths due to cardiac arrest have been attributed to the use of Flash-Ball by police.
