Firestorm Squadron was RC-328851 'Flashback's old squadron when he went by the nickname 'Relay'. During the Battle of Geonosis, Firestorm Squad was assaulting a droid factory inside one of the smaller spires on the planet, as a nearby Trade Federation coreship was making it's way into space. The TF coreship took heavy fire from SPHA-Ts on the surface, and at least two Republic warships in orbit. The mammoth sphere shaped craft lost control and started to fall back to the planet. Since 'Flashback', then known as 'Relay', was assigned to stay outside the spire as lookout, he could only watch in horror as the coreship crashed into the factory in which his brothers were fighting. 'Relay' was found two hours later by a clone battalion under the command of Jedi Master Crouse. A week passed and his physical wounds healed. 'Relay' was then reassigned to Nexu Squad, to replace a man they lost at Geonosis. Shortly thereafter, 'Relay' started to have horrible replays of the final moments he remembered from the battle in which his squad was killed.
