Imperial shock troopers, also known as Coruscant shock troopers and Imperial clone shock troopers, and as clone shocktroopers and clone guards under the Galactic Republic, were elite stormtroopers who served in the Coruscant Guard of the Galactic Empire. During the Clone Wars, the shock troopers were specialized clone troopers who served as a security police force on the planet Coruscant, the capital of the Republic. Noted for their distinctive red and white clone trooper armor, they supplemented the Senate Guard as bodyguards for galactic senators and Supreme Chancellor Sheev Palpatine. In addition to protecting the government facilities and officials of the Galactic Senate, shock troopers specialized in guarding prisons, maintaining civil order as anti-riot police officers, and escorting diplomats for off-world assignments.
