Chi Galaxy (Clan Steel Viper)
|Unit Profile (as of 3075)|
|Parent Formation||Clan Steel Viper Touman|
Chi Galaxy was intended to become the fifth Steel Viper front-line galaxy under a plan run by former Khan Natalie Breen in the 3040s, to be designated "Epsilon Galaxy". After the losses during Battle of Tukayyid, the plan was shelved and it remains the smallest of the garrison Galaxies. 
The Galaxy was brought forward to the Inner Sphere and deployed on two systems facing the Lyran border. The Galaxy appeared to have fared well during the retreat from the Occupation Zone, but by 3067 it could effectively field only two clusters worth of troops as other galaxies picked it clean to resupply themselves with warriors and 'Mechs. 
One of the last actions fought by the Vipers against the Society rebellion was the invasion of Circe. Beta Galaxy supported by Chi Galaxy landed on the planet after the Clan Watch had disabled the SDS. The Vipers destroyed a cluster sized bandit force and then spent two months rooting out the rebels.
IlKhan Andrews' violation of the Council's rules and traditions by shooting Khan N'Buta during the meeting pushed the Cloud Cobra Khan Hollyann Kardaan to condemned the act as evidence of the Steel Vipers' corruption, calling for an Annihilation of the Clan . Chi's last stand came on Circe. Two hundred DropShips of the combined Homeworld Clans landed troops on the planet despite the fire of the SDS ground batteries. Unable to fight off the combined home world Clans the Vipers and Chi Galaxy were wiped out in 3075.
