Plasma pulse discharger

The Plasma Pulse Discharger was a weapon used by the Dreadnought Battle Tank during the Battle of Thule. The weapon is fired by charging up then releasing a powerful purple shockwave all around the Dreadnought Tank causing enemy vehicles to not work properly for a brief amount of time which could leave them open for the Dreadnought to finish them off with its concussion missiles. Strangely in the video game Star Wars The Clone Wars, when it charges up,the sound is very similar to the AAT when it charges up its large cannon.
