An Imperial riot trooper on Kamino.

"I swear this sacred oath that I shall render unconditional obedience to Emperor Palpatine, to exercise every power in service to the Galactic Empire, and shall, whensoever I am asked, be prepared , as a loyal servant, to surrender my life for this oath."
―The Oath of Obedience

Imperial riot troopers were Imperial units trained for riot suppression in the Force Unleashed II. They were seen on Kamino , Cato Neimoidia, and several other planets. Riot troopers used electro staffs and had armor similar to a stormtrooper's.
