XXIII Corps (or the Twenty-Third Corps) was one of the seventy-two Corps that made up the Star League Defense Force. Prior to the collapse of the Star League XXIII Corps was a large corps, consisting of six divisions and 2 independent regiments.[1][2]


In 2764 XXIII Corps was part of the 15th Army, assigned to District 2 of the Draconis Combine Military Region. Assigned to garrison the border between the Combine and the Federated Suns, an area that was full of tensions, the XXIII Corps would rotate its forces through the region on a regular basis. This rotation of units allowed the XXIII Corps to supplement the patrols of the XXXIII Corps, which was the only unit assigned to the border from Third Army. XXIII Corps was headquartered on Capra.[2]

Despite the frequent action along the border, the XXIII Corps commander (Major General Tamara Polaski) would frequently accompany the 84th Light Horse Regiment to visit the various garrison locations of the Divisions under her command. When they arrived, the 84th and the host division would engage in wargames. General Polaski then spent a month with the host division's staff reviewing the exercise's results. This insured that each division was both up to strength, tactically sound, and familiar with what their Corps commander expected them to do in case of emergency.[2]

XXIII Corps (like all units of the 15th Army) couldn't draw on many local Combine military manufacturers. The XXIII Corps had an advantage however, in that it was garrisoning the area contested during Operation SMOTHER. This allowed the Corps to use the SLDF resupply facilities installed to support that operation. The largest of these facilities was on Benet III, and the XXIII Corps took possession of 'Mechs and armor produced on Marduk, Hun Ho, and Luthien.[2]

When the simmering violence and rebellion building in the Periphery erupted with the New Vandenberg Uprising and subsequent Periphery-wide uprising in 2765 XXIII Corps was deployed into into the Periphery Military Region along with the rest of the 15th Army.[1]

XXIII Corps took significant losses in the Periphery Uprising; not only were the 106th Mechanized Infantry Division lost in combat along with the Kursk Division, but the Caph Division took such heavy losses that it was disbanded in 2766, with elements of the division having joined the Periphery rebels. The Hegemony Campaign claimed more of XXIII Corps, with the Turkistan Hunters and the 29th Infantry Division lost in combat along with the independent 189th Light Horse Regiment. The 63rd Mechanized Infantry Division also took heavy losses in the campaign; by 2784 the division had been disbanded, with elements of the division joining the Free Worlds League and Lyran Commonwealth.[1]

When General Aleksandr Kerensky led the bulk of the SLDF on the Exodus in 2784 the majority of XXIII Corps chose to follow him; the exception to this was the 84th Light Horse Regiment, who signed on with the Capellan Confederation.[1]
