When General Aleksandr Kerensky launched Operation EXODUS and led the bulk of the surviving SLDF out of the Inner |Sphere in the wake of the Amaris Civil War, to eventually become the Clans, only one surviving RDMAF chose to remain behind.
This unit joined the Armed Forces of the Federated Suns accordingly and became the Fourth Deneb Light Cavalry with enough personnel to facilitate a number of other regiments.
