Solar Auxilia - Personal Arms: The most singular and perhaps iconic piece of wargear utilised by a member of the Solar Auxilia is their void armour; a carapace-reinforced, full environmental combat body armour with a fully integrated life support unit. The void armour worn by the Solar Auxilia, eponymously classified as "Solar Pattern", is itself a mass-produced modification of the ancient void armour worn by the Void Hoplites of the Saturnyne Ordo.The armour is fully sealed and capable of resisting small arms fire, ballistic impacts and shock trauma, is self-healing against minor penetrations and lacerations, and is particularly resilient against radiation and thermal effects, making it highly effective for combat operations in hostile environments of many kinds, not simply the open void. Although efficient and resilient, void armour should not, however, be considered to be a match in regards to durability or sophistication to Legiones Astartes power armour, which operates at a greater order of magnitude in terms of defence and endurance.Based on designs ceded to the early Imperium by the military forces of the Saturnyne Domains during the unification of the Sol System, the void armour of the ancient Imperial Army's Solar Auxilia regiments has become largely synonymous with that legendary elite fighting force itself. Designed to allow warriors to operate in some of the harshest conditions possible, void armour provides both a high degree of protection and a limited life support capacity. Offering a degree of environmental and combat protection exceeded only by the power armour of the Legiones Astartes, void armour, as its name implies, is intended to enable a Human soldier to survive the deadly travails of space battle and the harshest of exo-planetary conditions.Void armour is a carapace-reinforced, full environmental combat body armour integrated with a life support unit. The void armour worn by the Solar Auxilia, eponymously classified as "Solar Pattern," was itself a mass-produced modification of the ancient void armour worn by the Void Hoplites of the Saturnyne Ordo.All of the patterns of void armour were primarily based around a series of interlocking plates, which were enhanced with a servo-motor armature to allow a normal Human to bear the weight of the void armour. It also provided a high degree of protection and a limited life support capacity. All in all, the void armour was a significant improvement over the more common Flak Armour that was issued to regular Imperial Army troopers. A pattern of Reinforced Void Armour and Heavy Void Armour also existed to provide even greater protection to Solar Auxilia troops when fighting in Zone Mortalis environments, though at the cost of increased weight and decreased mobility.Just as the void armour worn by the Solar Auxilia is greater in terms of sophistication and material cost, so is its small arms weaponry, the most common of which was the Kalibrax V-I Pattern Lasrifle. The Kalibrax Lasrifle operates within the standard assigned power ranges set down by the Divisio Militaris for Imperialis Auxilia weaponry, but was notable both for its heavily reinforced energy transfer capacitors, overall durability and superior heat dissipation qualities over more common patterns such as the Mars Mark II Lasgun or the Ursh-Vantovka Lascarbine.These factors made it highly desirable for the hazards of void warfare and also easily able to handle a variety of modifications and augmentative systems, such as bolt-collimator arrays and induction blast-chargers, without the fatal strain such devices might impose on lesser weapons.Historically, in terms of light support and specialised weaponry, the Solar Auxilia always favoured various forms of directed energy weapons, including Flamers, Meltas, Multi-Lasers and Lascannons, particularly for their suitability to void combat and to simplify maintenance and munitions supply, although bolt and Rotor Cannon-type weapons were far from unknown in the cohorts, particularly when a Solar Auxilia cohort had operated for long periods alongside other Imperial forces.Once the standard armament of a significant number of infantry sections, Volkite Weapons became increasingly rare as the Great Crusade wore on, and by the Horus Heresy became the preserve only of the most elite of their Veletaris units. To carry such a weapon became a thing of great distinction in the ranks of the Solar Auxilia, the weapons themselves passing from soldier to soldier as time went on.The weapons of the Solar Auxilia's officer class had a tendency to be highly idiosyncratic in nature, with each officer allowed to furnish their own personal arms, allowing for considerable variation and indeed competition between them, with the sword of various forms being held commonly as the mark of an officer.Duelling between officers of similar rank outside of active war was always permitted within certain parameters within the Solar Auxilia, both as sport and more lethally over matters of honour (with a commanding officer's permission). For this the Terran Charnabal Sabre was the most common implement, and the training and skill this encouraged was seen as being purely beneficial to those involved and the cohorts they served.
