Guardsmen 124 was a legendary Saber Guard major. He commanded a specially elite group of the Saber Guard, called Saber Squad. He and this unit fought on Kamino during the Fourth Jedi Purge when Jedi Resistance ships attacked the planet. They were all defeated, but the squad suffered heavy casualties: 124 was the only survivor. The cloners didn't want to clone any more of them, so 124 was left without a squad after the battle. 124 and CC-2009 were bitter rivals.
