CR57
this was the callsign of one of the clone trooper commanders who were dispatched to the planet Thustra, during the height of the Clone Wars. The battle group had been dispatched to establish a beachhead on Thustra and make a strong show of force, without engaging the native Sephi in any way. The Sephi, however, were not going to remain with the Old Republic under any circumstances, and attacked the Republic's forces as soon as they arrived. CR57 and his squadron were among the first to encounter heavy resistance, and also among the first to die in battle.
