Graaqu Namec was a member of the stormtrooper corps, serving under the command of General Brenn Tantor throughout much of the Galactic Civil War. After Tantor was incarcerated on Kalaan for refusing an order to execute civilians, a fellow stormtrooper, Gana Lant, persuaded Namec along with eight other stormtroopers who had been under Tantor's command to prioritize loyalty to the man who had led them through numerous battles over the Galactic Empire, which had betrayed him.
Grand General Malcor Brashin made a disastrous decision by assigning them to guard Tantor in his open-air prison cell. Lant liberated Tantor and conveyed the squad's allegiance to him. With Tantor now free, the stormtroopers commandeered the TR-MB prototype and launched an assault on the prison, successfully freeing Luke Skywalker. The group journeyed through the canyons of Kalaan, gaining support from the Kalaanite resistance until they reached a Rebel base established by Tyr Taskeen. From that location, they were transported to Taskeen's fleet, where it is assumed they were temporarily detained along with their general. Upon their release, it is highly probable that they continued to serve the Rebellion as infantry under the leadership of Tantor.
