Mk II EMP grenade

The Mk II EMP grenade was a model of Electro Magnetic Pulse grenade manufactured by SoroSuub Corporation specifically for use by the Galactic Republic's Grand Army of the Republic. The grenade cost three hundred credits and was the same size as a standard fragmentation grenade and released a powerful electromagnetic pulse capable of disabling droids or electronic systems rather than an explosive force. During the Clone Wars, it was the latest weapon in the world of anti-droid weaponry.
