"EMP grenade technology is out there, but I've never had my hands on one," said Col. Laurie Buckhout, chief of the newly formed Electronic Warfare Division, Army Operations, Readiness and Mobilization, during a February 2009 bloggers roundtable from the Pentagon.
Hand grenade size units implies that there are larger EMP devices and High Power Microwave units.
The Taser XREP is an electrically charged dart that can be fired from up to 20 metres away with a 12-gauge shotgun. Upon impact, its barbed electrodes penetrate a victim's skin, discharging a 20-second burst of electricity to "distract, disorient and entice the subject to grab the projectile", says Taser.
Commercial production of the XREP is due to start later this month, with US police departments and the US military expected to be using the weapons by the end of 2009.
The Auto Assault-12 (AA-12) shotgun (originally designed and known as the Atchisson Assault Shotgun) seems to have a range of 175 meters for mini-grenades and would seem to be compatible with the Taser XRep.
