Planetary HistoryEdit

Victoria WarEdit

When Jacson was invaded by the Federated Suns during the Victoria War the mercenary unit Lethal Injection were under contract to the Capellan Confederation to defend the planet. Lethal Injection retreated into the Perpetual Forest in the face of the invaders numbers. The massive boughs of the trees in the Perpetual Forest played havoc with the sensors of pursuing units; however, the Armed Forces of the Federated Suns task force included the mercenary unit Holt's Hilltoppers, who had been under contract to the Capellan government themselves before taking up a contract with the Federated Suns. The Hilltoppers deployed the recon company Champion Battalion into the Perpetual Forest in pursuit of Lethal Injection; with the disruption caused by the mighty trees, neither force was able to detect each other and the two literally stumbled across each other.[30]

The Hilltoppers were able to use their greater numbers - and the lance of light, fast Koshi BattleMechs within their recon company - to eliminate the recon component of Lethal Injection, and as a result the Capellan mercenaries pulled back out of the Forest and retreated from Jacson; the Federated Suns assumed control of the planet shortly afterwards.[30]

Jacson was one of the first worlds invaded during the Victoria War. The 1st Federated Suns Armored Cavalry and 8th Syrtis Fusiliers were the lead AFFS units on the world. It was also the site of the Spaceport Massacre, where a renegade Major from the Syrtis Fusiliers tried to steal a cache of Germanium. The Major and his associates had seized a Mule and Lung Wang DropShip, and the Mule carried civilians he used as hostages and human shields. After both DropShips lifted off, the Lung Wang opened fire on the Mule and caused it to crash. The resulting explosion killed all the hostages as well as destroying several kilometers of the spaceport as secondary explosions from fuel and munitions stored there exploded.[31]
