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. 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. During the Clone Wars, the shock troopers were specialized clone troopers who served as a security police force on the planet Coruscant, capital of the Galactic Republic.
Imperial shock troopers, also known as Coruscant shock troopers or clone guards, were elite stormtroopers who served in the Coruscant Guard.
