As part of a program initiated by the Primarch Roboute Guilliman, seeking to grant a Legion strike force access to highly specialised weapon systems without the need to employ numerous vehicles for each role, the Sicaran hull was chosen to mount the newly developed twin Arcus launcher. Capable of deploying a wide range of warheads, each crafted to fulfil a distinct tactical niche, the Arcus was intended to become the cornerstone of a new tactical doctrine the Master of Ultramar had begun to formulate, allowing small Legiones Astartes forces to operate without extensive support and in smaller numbers than during the Great Crusade. Despite being limited to a few prototype vehicles at the onset of the Horus Heresy, and the doctrinal issues that kept it out of production on most major Forge Worlds, a number of Legion home worlds produced small numbers of this variant. Of particular note is the inclusion of the neutron-flux warhead, a Terran development dating back to the years prior to the alliance with Mars. Continued production of these weapons was the cause of the Mechanicum’s refusal to sanction the Arcus pattern hull.

The Space Marines of the Emperor’s Legions are genetically engineered, psycho-indoctrinated warriors with superhuman abilities, and minds and souls tempered for war. Each of the Legions has its own idiosyncrasies and character – the product of their gene-seed and the unique warrior cultures fostered by their masters.
Any unit with this special rule will have a number of additional special rules and abilities specific to their ‘named’ Legion, all of which will be defined in other Horus Heresy – Age of Darkness publications. A Space Marine unit may only have one such ‘named’ rule, e.g., Legiones Astartes (Sons of Horus). Space Marine units from a different Legion may only be included in an army using an Allied Detachment and in conjunction with the Allies in the Age of Darkness chart.Some weapons are capable of breaching armour with a terrifying ease, whether by specially designed munitions, careful targeting or sheer brute power.
When rolling To Wound for a model that has the Breaching (X) special rule, or is attacking with a weapon that has the Breaching (X) special rule, for each To Wound roll equal to or higher than the value listed in brackets, the controlling player must resolve these wounds at AP 2 instead of the weapon’s normal AP value. This rule has no effect on models that do not have Wounds, such as models with the Vehicle Unit Type.The helical targeting array is a complex system of augurs and tracking baffles. It is designed to enable a war machine’s weapons to strike true, even against the most evasive targets, and to penetrate even the most esoteric of shrouds.
The controlling player of a model with a helical targeting array may activate it at the start of any of their own turns, or, if the controlling player is not taking the first turn of the battle, at the start of the battle, before the beginning of the opposing player’s first turn. Once the helical targeting array is activated, the model is affected by the following conditions until the beginning of the controlling player’s next turn:Many armoured fighting vehicles bear simple grenade systems rigged to distribute smoke upon being triggered, granting the vehicle a brief and passing cover that can prove crucial in the worst of situations. Such devices are of most use in slow moving engagements, as a vehicle at maximum speed will quickly disperse or outrun its own smoke shield.
The controlling player may choose to trigger smoke launchers once a model with them has completed its movement in the Movement phase, and may only choose to trigger them if the model has moved no faster than Combat Speed that turn. Once triggered, the model with smoke launchers counts as being more than 25% obscured, regardless of terrain, until the start of the controlling player’s next turn and gains a 6+ Cover Save. A model whose smoke launchers have been triggered may not make any Shooting Attacks, except as part of a Reaction, in the same turn. Smoke launchers may only be used once per battle, and once triggered may not be further used – in addition, they do not count as a weapon and may not be targeted by Weapon Destroyed results on the Vehicle Damage table.Mounted illum-beacons or simple electric torches, many vehicles mount some kind of portable light to aid in target identification and destruction in darkness and poor weather.
A model with searchlights ignores the 24" limit to line of sight imposed by the Night Fighting rules when making Shooting Attacks, however enemy units also ignore that same restriction when making Shooting Attacks that target a model with searchlights.This datasheet has Heavy Support Battlefield Role. Full list of Legiones Astartes units sharing same Battlefield Role follows:
Designed specifically to degrade the complex neural circuitry and cogitators of the Mechanicum’s automata, these weapons are considered an affront to their Order. The exotic radiation emitted by such devices is the bane of the otherwise indefatigable steel warriors of the Mechanicum, leaving them as motionless, lifeless husks.
A weapon with this special rule gains the Instant Death special rule when targeting models with the Automata Unit Type.
