Following the New Vandenberg Uprising and subsequent Periphery uprising the 275th was deployed into the Periphery. The 275th survived their Periphery deployment and the Hegemony Campaign; the bulk of the division chose to follow General Aleksandr Kerensky on the Exodus but one of the regiments - the 104th Striker Regiment - chose to remain behind in the Inner Sphere and joined the Draconis Combine.[1]
