The Rojo Caballero was a civilian DropShip that joined the Secret Fleet built by Admiral Dmitrios Rummolo in the wake of Operation APOTHEOSIS, the coup launched by Stefan Amaris of the Rim Worlds Republic to take control of the Terran Hegemony and, through the Hegemony, the Star League itself. Admiral Rummolo took command of the Star League Defense Force Ninth Fleet for the campaign to liberate the New Earth system as a part of Operation CHIEFTAIN in 2776; as a part of his plan, the Rojo Caballero and two other civilian vessels - the DeBritta and the Memphis Tale - were modified extensively to incorporate hidden capital weapons.
Rummolo led an unconventional campaign from the outset; having obtained approval to destroy the HPG in the New Earth system, as the need for security - and the need to prevent the SDS network sharing information on SLDF tactics, techniques and procedures - outweighed the need for the HPG, which could be replaced on a temporary basis by mobile HPG systems. The attack on New Earth began with the three modified civilian vessels, who rained volleys of missiles down on the HPG site as well as key command and control nodes on the planet. Although all three modified civilian DropShips were swiftly destroyed by Amaris Empire Armed Forces AeroSpace Fighters they managed to hit their targets and played a vital part in the liberation of New Earth.
