XLV Corps (or the Forty-Fifth Corps) was one of the seventy-two Corps that made up the Star League Defense Force. Prior to the collapse of the Star League XLV Corps was a fairly large corps consisting of seven divisions, nine independent regiments and an independent aero wing.[1]


In 2764 XLV Corps was part of the 18th Army assigned to the Outworlds Alliance Territorial State. They were the core of the 18th Army and were headquartered on Alpheratz. The Forty-fifth Corps was nicknamed the "Union Holders" by the citizens of the Alliance; The name refers to Operation UNION HOLD, the SLDF's campaign in the Alliance during the Reunification War. The Forty-fifth had difficulty getting along with citizens of the Alliance, but the SLDF High Command had changed commanders and hoped that this would alleviate the tensions.[2]

When the simmering violence and rebellion building in the Periphery erupted with the New Vandenberg Uprising and subsequent Periphery-wide uprising in 2765 XLV Corps were swept up in the violence along with the rest of the 18th Army.[1]

XLV Corps was badly mauled during the Periphery conflict, with four divisions, four independent regiments and the independent aero wing all destroyed during 2765. In addition to those units destroyed in 2765, the 247th Heavy Assault Regiment took heavy losses, and was disbanded in 2766.[1]

By the end of the Hegemony Campaign XLV Corps was a shadow of its former self; the Flanders Division had been disbanded due to heavy losses, while the Democrats of Brazil had been destroyed along with the 150th Hussar Regiment and the 587th Heavy Assault Regiment. While it's known that the Tobruk Division survived the campaign, the final fate of the division is unknown. Two of the surviving independent regiments, the 279th Light Horse and the 128th Hussar followed General Aleksandr Kerensky when he led the bulk of the SLDF on the Exodus in 2784. The third surviving regiment, the 396th, remained in the Inner Sphere and joined the Federated Suns.[1]
