Non-lethal grenades have been employed by prison guards, law enforcement officers, and military personnel to temporarily disorient or disable individuals such as suspects, rioters, and combatants.
Generally, there are two types of non-lethal grenades—blunt trauma grenades, also known as rubber ball or sting ball grenades, and stun grenades, also known as flashbangs.
Blunt trauma grenades achieve cause a disabling effect by projecting rubber spheres at a non-lethal velocity. Flashbangs emit a 2.5 million candlepower light flash and a loud bang (~170-180 decibels).
Many of these grenades focus only on a single effect and not on any secondary effect that may be desired. Unfortunately, this may require warfighters or law enforcement officers to carry multiple types of grenades.
Additionally, blunt trauma grenades are potentially lethal if the metal fuse strikes a human. The requirement to have the fuse eject without becoming a lethal fragment and remain functional across all conditions causes many production and handling issues, which reduce the reliability and increase the life cycle unit cost of each grenade.
The U.S. Army has addressed these issues with a new non-lethal grenade design that uses blunt trauma, sound, and light to disorient and incapacitate targets. The design eliminates the need for an ejectable fuse by balancing the gas output of the main charge of the grenade, which prevents the fuse from becoming a lethal projectile. As such, the grenade overcomes the safety, predictability, and reliability issues associated with an ejectable fuse. The complexity of operation is also reduced by eliminating the ejection charge and the need to have two independent fuses function cooperatively.
