Leading from the front, Julian Davion and his Templar III 'Mech were carried on the Kingsman when Task Force Styx of Operation CERBERUS assaulted New Syrtis on 4 December 3147 to retake the planet from the Capellan Confederation. At the time, the Kingsman was captained by one Captain Chastain.
In this two-pronged attack, the Kingsman was part of the force that jumped into the New Syrtis system at the L2 jump point of the planet's moon, Varnay's Star. They were immediately beset by Capellan Assault DropShips and aerospace fighters and the Kingsman suffered at least some hits in the engagement, though it was not critically damaged and would go on to serve the First Prince in the successful offensive.
