The Service Special was a small blaster used by Imperial law enforcement agency officers.
Developed around 4 BBY, the Service Special was only half the size of most blasters but possessed six times the power, and was a secret even from some elements of the Imperial military. Its power was roughly equal to one of the four cannons in the Millennium Falcon's quad-guns.
Corrupt officer Waywa Fybot used this weapon to kill Bassi Vobah during the raid on Bohhuah Mutdah, literally disintegrating her head.
