Unit Brief[edit]

The 431st Division was a ComStar Combined Armed combat force consisting of a Division worth of 'Mechs, Combat Vehicles, Aerospace Fighters and Infantry.[1]


The Division was first revealed to the public in the 3030s, when ComStar began to deploy 'Mech armed units throughout the Inner Sphere. The Division was assigned to the 7th Army, stationed on the Free Worlds League planet of Camlann as part of the HPG Station's garrison force.[2][3]

Near the end of the Clans' invasion, the unit redeployed with the rest of the 7th Army's components to Tukayyid. Once there, the unit was designated as a reserve unit. 7th Army's was assigned to defend the cities of Joje and Tost from Clan Nova Cat as part of the massive proxy battle for possession of Terra in 3052.

After the Nova Cats made their landing, its fellow Comstar units were able catch Clan's forces by surprise and decimate components of Alpha Galaxy. Units of 7th Army and elements of the 12th Army engaged Gamma and remains of Alpha as they tried to push ahead to Joje. As the Clan Galaxies struggled, reinforcements appeared in the form of the 44th Nova Cat Cavaliers from the Cat's Beta Galaxy. The 431st Division and the 13th Division were lying in wait alongside the road that the Cavaliers were taking. They caught the unsuspecting Cluster completely by surprise and utterly devastated them, preventing from linking up with their beleaguered fellow Clansmen.[4][5][6]
