Rare even at the height of the Great Crusade, Primus Redoubts are specially constructed by teams of Mechanicum thralls and Tech-Priests for specific engagements. The most common use for such fortifications is to repel enemy super-heavy vehicles, though on some occasions they have been pressed into service to counter lone titans, but the sheer power of its armament allows it to annihilate lesser vehicles with ease. Commanders must be wary of enemy infantry though, for the gun is ill-placed to deter such foes, leaving it vulnerable if left undefended.

These huge weapons are intended for the long range destruction of key enemy assets and are not equipped for rapid retargeting or for tracking lesser targets.
A Weapon with this Special Rule may only be used to attack an enemy Unit that fulfils one of the following conditions:This datasheet has Fortification Battlefield Role. Full list of Battlefield Fortifications units sharing same Battlefield Role follows:
Some weapons trade precision for indiscriminate destruction, high explosive impacts that can devastate a wide area. From artillery shells to high energy blasts, such weapons are popular tools of destruction on the battlefields of the Horus Heresy.
Attacks made with the Blast (X) Special Rule use a Blast Marker to determine how many Hits are caused.Military buildings are often vital to defensive operations, serving to shelter vulnerable troops, mount heavy guns or deploy other technological defences. During the Horus Heresy almost every force made use of such defences, though they were rarely considered a decisive element in any order of battle.
The following Rules apply to all Models with the Fortification Type:Emplacements are either purpose built military structures or civilian buildings hastily converted to mount ranged weapon batteries. Given the limited nature of the systems that control these structures they cannot be relied upon to fight a battle alone, but can serve as a useful means of delaying or corralling the foe while more traditional troops act elsewhere on the battlefield.
The following Rules apply to all Models with the Emplacement Sub-Type:Mightiest of all the Emperor’s creations and the greatest warriors and generals of their age, the Primarchs of the Space Marine Legions epitomise the dark ages of the Horus Heresy. These colossi of war were powerful beyond the capabilities of any mortal warrior or steel-forged automata - for their only equal was another of their own kind.
The following Rules apply to all Models with the Paragon Type:Heavy beams and armour-piercing cannon rarely inflict superficial damage, but always blast and break the hull of their target. Such weapons are superior tank killers, their sheer power prized over lesser weapons when the objective is to apply maximum damage without concern for finesse.
A Weapon with the Armourbane Special Rule counts Glancing Hits as Penetrating Hits.Bunkers are fortified shelters for infantry, allowing them to find temporary respite on the battlefield. Some such structures also boast fixed weapons batteries, allowing troops to continue to fight even as they take cover.
The following Rules apply to all Models with the Bunker Sub-Type:Whether equipped with antigrav repulsors or empowered by some esoteric, psychic art, this unit is able to skim above the ground. While incapable of true flight, this does allow it to avoid any of the hampering effects of the prevailing terrain, gliding over obstacles that would ensnare or entangle more conventional troops.
The following Rules apply to all Models with the Antigrav Sub-Type:These huge weapons are intended for the long range destruction of key enemy assets and are not equipped for rapid retargeting or for tracking lesser targets.
