Even with the public expansion of the Com Guard to defend ComStar's myriad of HPG compounds, the full extent of the Terran Defense Force remained hidden. Not even the fearsome Wolfnet could pierce ROM's protective cloak, its best estimates was that the Defenders of the Faithful was a Level V sized beta formation with the strength of tweleve Regiments, two or more being BattleMech Regiments. [1]

The bulk of Com Guard portion of the Defenders of the Faithful served as an uncommitted reserve force slated to face Clan Wolf during the Battle of Tukayyid, assigned by Precentor Martial Anastasius Focht to an ad-hoc 13th Army, but the Wolves won the day before they could be fully committed.

With the terrible losses on Tukayyid, elements TDF were reassigned to bolster other divisions, with rebuilding formations assigned to take up the slack as they rebuilt, downgrading it to a gamma based formation. The post-Tukayyid TDF [2]

The mercenary unit Brion's Legion made up half of the Terran Defense Force. Their contract ran from the end of the Fourth Succession War to the beginning of Operation Guerrero. Their departure, and the subsequent hiring of the 21st Centauri Lancers, would eventually cause ComStar to lose Terra.[3]


As of 3050 the Terran Defense Force was under the command of Precentor Margo Koivu. [1]

As of 3055, the TDF was under the overall command of Precentor Ralph Marchino. [2]

As February 3058, the TDF was under the command of Precentor Lisa Koenigs-Cober. Only just named at its CO, Koenigs-Cober narrowly escaped the destruction of her DropShip during the opening shots of Operation Odysseus and would eventually assist in the rescue of Primus Mori and withdraw to Tukayyid. Despite her expectation she would be reprimanded for actions on Terra, Koenigs-Cober would ultimately rise to command of the 472nd Division.[4]
