Although they were able to defend themselves against the clone's dual lightsabers, they were completely helpless against his genetically-inherited Force powers. During his break out, many riot troopers attempted to neutralize the rogue clone's progress, but were ultimately killed for their efforts. However, the procedure was initially imperfect and resulted in numerous abject failures, including an emotionally unstable clone who escaped from Kamino. Six months after the formation of the Alliance to Restore the Republic, the Sith Lord Darth Vader commissioned a clandestine project to recreate his fallen apprentice, the late Galen Marek, through an experimental type of Kaminoan cloning technology. In 1 BBY, roughly a year into the Galactic Civil War, several riot troopers were killed, along with many other Imperial troopers, in the Timira City Cloning Facility of Kamino. However, when faced with direct weaponised conflict, riot troopers were forced to call in standard stormtroopers. Because they were trained specifically for confronting and putting down large-scale civilian insurrections, they lacked any fear of being overwhelmed by crowds. In combat, they were often accompanied by a squad of stormtroopers the troopers provided aid from a distance with their range weapons while the riot troopers closed in on the enemy with their electrostaffs. Every riot trooper was required to swear the Oath of Obedience upon graduation as a symbol of their unquestioning loyalty to the Emperor and his Empire-an oath that could only be severed through death. The riot troopers' special status was emphasised by the fact that they received training at an Imperial Royal Guard Academy on Yinchorr, the same facility where Emperor Palpatine's Royal Guardsmen were trained. In addition to their weapons, the riot troopers wore protective suits that slightly resembled the armor of the Imperial stormtroopers. As a consequence, they lacked any type of range weapon.

As military enforcers of the Empire, the riot troopers were typically stationed on subjugated worlds throughout the galaxy, such as Kamino and Cato Neimoidia, although they were most common on megalopolis worlds throughout the Core and Colonies due to them being disobedient worlds, that according to the Empire, required 'parental discipline.' They were trained for close-combat, and thus were armed with electrostaffs, made from lightsaber-resistant cortosis. Riot Stormtroopers, colloquially known as Riot troopers, were highly-trained soldiers that specialized in containing and defusing insurrectionist scenarios due to the spread of the influence of the Rebel Alliance to even within loyalist populations in the Galactic Empire. ' 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
