Aquilon Terminator Squads were a specialist formation of veteran Custodians that served in the ancient Legio Custodes, the elite bodyguard of the Emperor of Mankind, during the Great Crusade and Horus Heresy eras during the 30th and early 31st Millennia. This elite formation was arrayed in formidable Aquilon Pattern Terminator Armour, a more complex form of standard Cataphractii Pattern Terminator Armour that possessed additional integrated power systems and capacitors. To augment their formidable armour they had access to a deadly array of weaponry including - Solerite Power Gauntlets, Adrathic Destructor, Lastrum Storm Bolter or Infernus Firepikes. It is unknown if these elite squadrons are still deployed by the modern era Adeptus Custodes of the 41st Millennium.
Although the Tactical Dreadnought Armour project was conceived first and foremost for the use of the Legiones Astartes, it was inevitable given the success of Terminator Armour that its principles could also be adapted for Legio Custodes use. The first pattern developed was what became known as Aquilon Armour. Advancing yet further upon the Cataphractii Terminator armour patterns, the Aquilon pattern takes into account the enhanced physique of the Legio Custodes as being able to bear more weight and strain than even a Space Marine, and so is fitted with additional integrated power systems and capacitors which make up for some of the limitations of the origin pattern. This allows for the Cataphractii Terminator armour's famous durability to be retained in the Aquilon pattern, but with a degree of speed and manoeuvrability the former lacks.
Within the ranks of the Legio Custodes, Aquilon Terminator Sodalities were employed rarely but as need dictated, particularly on those rare occasions where the Legio Custodes were required to operate under conditions designated as "Zone Mortalis" or required to storm a breach. In such operations, the Legio was loathe to risk unwarranted loss of life, and the superior defences of the Aquilon Terminator Armour was relied upon to mitigate the risk as much as possible as well as provide a platform of mobile heavy firepower.
Aquilon Terminator Squads were primarily found within the ranks of the Tharanatoi, the counter-assault forces of the Legio Custodes. Though there were few opponents that the Hykanatoi could not deal with, they were not a rounded military force in the sense that they were not configured to deal with exigencies such as siegecraft or attrition warfare that fell outside their purview. However, the Legio Custodes still maintained the ability to deploy its forces as heavy shock troops should the need arise, or indeed to counter a foe that directed overwhelming force against it in high-intensity warfare. The Tharanatoi encompassed custom-modified suits of Terminator Armour optimised for use by the Custodian's superhuman frame, as well as vastly potent portable firepower such as carried by the Sagittarum Guard, whose weapons include those few dark relics known as Adrathic Weapons - disintegration beams of phenomenal destructive potential, long gathered to the Emperor's household and entrusted to no other.
