Cadia has a special and honoured place in the history of Mankind. Cadia stands upon the edge of the Eye of Terror within a narrow corridor of stable space called the Cadian Gate. This forms the one and only predictable passage between the Chaos infested Daemon worlds of the Eye of Terror and Earth. No battlefleet of any size can rely upon other unstable passages, but must pass through the Cadian Gate. Cadia is therefore one of the most strategically important planets of the galaxy.

On several occasions the forces of Chaos have moved against Cadia and raging battles have been fought in the deeps of space. Such huge battles are rare, but the constant intrusion of Chaos raiding craft is commonplace. Chaos Space Marines make frequent forays onto the surface of Cadia, and must be hunted down. The most powerful fighting formations of the Cadian forces are called Cadian Shock Troops. They are chosen from the best of the Cadians. As all Cadians must train in the defence forces, these fighters are quickly identified and inducted for further training.

When playing with a Cadian Shock Troopers force we recommend you use the list from Codex: Imperial Guard using the following doctrines:

• Grenadiers
• Sanctioned Psykers
• Special Weapon squads
• Storm Trooper squads
• Iron Discipline
• Sharpshooters
• Conscript platoons

Preferred special weapon: Grenade launcher
Preferred heavy weapon: Autocannon
