Clone Troopers

Clone troopers were an army of identical, genetically-modified clones, created to serve in the Grand Army of the Republic during the conflict that came to be known as the Clone Wars. Grown and raised in the laboratories and facilities of Kamino, the clone troopers were trained throughout the first ten years of their lives to become one of the most efficient military forces in galactic history. Bred for the sole purpose of combat, the clones were indoctrinated with unwavering obedience to the Galactic Republic and—more specifically—their Commander-in-Chief, the Supreme Chancellor.
