The 423rd Royal BattleMech Division was a part of the Star League Defense Force Regular Army. It was one of the SLDF's Royal units, which consisted of troops from the Terran Hegemony.


The Division was formed in the 2720s as part of a military build up by First Lord Jonathan Cameron.[1]

In 2764, the unit was assigned, as a part of the LXVII Corps, Twentieth Army, to the Periphery Military Region, but was moved to an undisclosed area of the Periphery by 2765, to take part in the Periphery Uprising.[2] The 423rd was destroyed during the Hegemony Campaign.[2]


The commanding officer in 2764 was Major General Mirielle Beaugois.[1]


As an SLDF BattleMech division the 423rd would have been formed from two Brigades of BattleMech regiments and a brigade of Mechanized Infantry regiments.[3]
