Rocket stormtroopers were equipped with missile launchers such as the RPS-6 rocket launcher. They were trained to eliminate insurgent activity, diminish uprisings and quell dissent, providing ground support. Though effective, their weapons required them to reload after each shot, leaving them vulnerable. Some rocket stormtrooper armor's right shoulder plate featured a red symbol.
Five years into the Jedi Purge, rocket stormtroopers were stationed on Zeffo, the Imperial Refinery on Kashyyyk, Ilum, and the Fortress Inquisitorius on Nur, where they encountered and were defeated by the Jedi Padawan Cal Kestis.
