Proton grenade

Proton grenades were small packets of explosives that were either thrown by hand, loaded into morters, and sometimes loaded into a ship's missile launchers. These grenades were activated by flipping a small switch on one side, and exploded on contact.

They were used mostly by the CIS, Rebels, planetary defence forces, and smugglers. However, they were also occasionally used by the official military, (Old Republic, Empire, New Republic), but the Thermal detonator was generaly prefered.
