Stance, known only by the number CT-1157 until the skirmish on Kardoa, was a clone trooper who served in the Galactic Republic's Grand Army under Jedi General Depa Billaba. At the time of the skirmish on Kardoa, he was new to the battlefront and thus regarded as "green" by his superiors. He and the young Padawan Caleb Dume struck up a friendship, and when Dume was wounded and rendered unconscious during a skirmish, CT-1157 defended him from the Separatist droids. Following this, he won a commendation of valor and earned the name Stance. Soon after, Stance and the rest of the battalion were sent to Mygeeto, but during the battle on Mygeeto he was killed by Colonel Coburn Sear.
After his death, Dume fought Sear. Towards the end of their fight Sear lit himself to kill both himself and Dume, but Dume killed the Kage Warrior. Not long afterwards, a funeral for Stance was held.
