The 103rd Nightbrothers were an elite battalion of clone troopers trained by their commander CC-1010 a.k.a. Commander X. They never lost more than 30 men in the entire clone wars. The battalion was led by Commander X, General Val Kepros, and Lueitenant Brazier. Commander X wiped out the entire battalion on Vardos when they conrnered a surviving jedi with the last member of the battalion being CT-5810 (The guy on screen). X suffers from PTSD for slaughtering his entire team.
