CT-26-1409, nicknamed "Echo," as he was known for "echoing" the standard rules and procedures established for clones, was a clone trooper who served in the Grand Army of the Republic during the Clone Wars. Around 22 BBY, Echo stood guard at Rishi Station, a listening post located on the moon of Rishi, where he and other rookie clone troopers were stationed. Under the command of Sergeant O'Niner, the group of clones maintained the listening post to warn the Galactic Republic fleet of any attacks on Kamino by the Confederacy of Independent Systems. The troops were present during a surprise Confederate attack on the station, when BX-series droid commandos took over the base and fortified themselves inside. After three droid commandos shot and killed O'Niner, Echo and the other rookie troopers evacuated the listening post through a ventilation shaft.
Outside, the clones witnessed two clone officers, Commander Cody and Captain Rex, arrive at the base shortly after the attack for a routine inspection. The two met up with Echo and the remaining clone troopers and organized a plan to attack the droids. Upon regaining control of the base with the other clones, Rex ordered the station's destruction to turn of its all-clear beacon and alert a nearby Republic fleet to the imminent Separatist attack. Echo suggested the use of using liquid tibanna, which was being stored in several plunk droids, to destroy the base. However, when the remote detonator to the liquid tibanna was unable to be connected to the explosives, trooper Hevy decided to stay behind and fix the problem before joining the others, while the other clones left the base through a ventilation shaft. Soon after Echo and the others evacuated the base, it exploded, resulting in the destruction of the droid forces and the death of Hevy, who had been unable to make it out. A LAAT/i gunship soon arrived and picked up the surviving clone troopers. On board the Venator-class Star Destroyer Resolute, Echo and fellow trooper Fives were rewarded with medals for their service and were inducted into the 501st Legion. ==
