The One Hundred Thirty-First BattleMech Division was a part of the Star League Defense Force Regular Army.


In 2762 elements of the Second Brigade of the Fusiliers of Oriente were training with the First Orloff Grenadiers on New Delos when they discovered a pirate raid.[1] The Second Fusiliers attempted to engage the pirate force, which Grand Duke Cedro Allison of the Duchy of Oriente believed to be under Maskirovka direction, when elements of the 131st BattleMech Division intervened and engaged the pirates directly.[2] The troops from the 131st - which were from the 1333rd Brigade - ended up having to surround the Second Fusiliers and order them to stand down after frustrated elements within the Fusiliers fired warning shots on the lead BattleMech company from the 1333rd.[1]

The news that battlefield control had been removed from Major Mykonos of the Fusiliers by the 131st on the grounds that the pirate raid was Star League business, rather than internal Free Worlds League business, infuriated the Grand Duke, in part because of the SLDF refusing to intervene in the earlier Marik Civil War on the grounds that the Civil War was internal FWL business.[2][1]

In 2764, the unit was assigned, as a part of the XIX Corps, Eighth Army, to Destrict 1 of the Free Worlds League Military Region and then transferred to District 3 by 2765.[3] The 131th survived the Periphery Uprising and the Hegemony Campaign, and followed General Aleksandr Kerensky on the Exodus in 2784.[3]

The 131st remained on the rolls of the Star League in Exile, but was greatly reduced in size. Ellie Kinnison, first khan of Clan Steel Viper, served as a Lieutenant in the Star League in Exile's 131st.[4]


As an SLDF BattleMech Division the 131st would have been composed with two Brigades of 'Mech regiments and one brigade of Mechanized Infantry regiments.[5]
