The fabled macro engines of the Centurio Ordinatus are rare and truly arcane technological wonders of staggering power. An esoteric weapon system capable of immense destruction, the Mechanicum Ordinatus Sagittar ranks among the smaller classes of Ordinatus, but nevertheless stands as a colossus of war and is one of the most potent war machines at the Imperium’s disposal. The Ordinatus Sagittar’s primary weapon system is a massive Belicosa pattern volcano cannon more commonly wielded by Warlord battle titans. This immense weapon is more than capable of obliterating most targets in a single blast and poses a significant threat even to the largest classes of titan. The sheer potency of this weapon has oft proved a double-edged sword, for such is its power that the appearance of such a vehicle on the front line makes it a priority target for enemy artillery. As such the Mechanicum has often been hesitant to deploy these rare Ordinatus to anything other than the most critical engagements.

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.The [Allegiance] Trait is used in the following Legio Titanicus datasheets:
Exotic beam weapons of arcing energy or sequential explosions triggered by the death of the first victim, some weapons cause not a single casualty, but a slew of them. Such weapons are wielded with grim efficiency against close packed formations of troops on the battlefields of the Horus Heresy. The most well-known examples are the volkite weapons of Mars, but many others are known.
Unsaved Wounds inflicted by attacks with the Deflagrate (X) Special Rule can cause additional Hits.This datasheet has Lords of War Battlefield Role. Full list of Legio Titanicus units sharing same Battlefield Role follows:
Unlike lesser war machines, a titan does not need to rely on the assistance of other warriors for its repairs, for within the metal hull of each such engine resides a dedicated repair crew.
A Model with the Repair Crew (X) Special Rule can repair itself.Specialised auspexes designed to efficiently target larger war engines at great distances are often fitted to the largest titan weapons. These devices allow the long range duels of such gargantuan engines to be conducted at distances too great for most targeting units, but are less use when targeting smaller, closer enemies.
When not attacking Titans, Knights or Super-heavies, a Weapon with this Special Rule must make Snap Shots.

Some weapons are so heavy that, while they can be fired on the move, are more powerful when properly braced and made ready before shooting. Warriors on the battlefield must use their judgement to decide when speed is required and when the full firepower of their arsenal must be unleashed.
