For all the shiny new models that the Sisters of Battle have received, it has occurred to me that their selection of vehicles is still rather limited. Whilst they've gained a few vehicular units (Mortifiers as an alt-build for Penitent Engines and that one special character's floating pulpit thing) their tanks are still restricted to the Rhino, Immolator and Exorcist. The Repressor does still exist, but only in Legends and not in actual production. And they're utterly bereft of anything bigger than a Rhino chassis.
So, my brothers and sisters, what vehicles would you like to see added to the Sororitas inventory? This includes existing vehicles from other Imperial departments given an Ecclesiarchal conversion (like the Rhino), forgotten vehicles from fluff gone by/the background of art, or even homebrewed ideas for that one conversion you've always wanted to make or whatever. The warp's the limit.
Here's some I dreamt up earlier, complete with fluff and "out of universe" conceptual thinking:
Castra Ferrum-Ignea Pattern Dreadnought:
Unfortunately, the pattern proved to be non-viable in practice; very few Sisters wounded to the point entombment was necessary survived the process due to lacking the increased hardiness of a Space Marine. As such the pattern was eventually discontinued from production, though some of these Dreadnoughts still exist and serve to this day. Such individuals are vaunted servants of the Emperor, considered living relics by the Orders they belong to.
Ignea Dreadnoughts are very rarely deployed in combat, due to their incredible rarity and irreplaceable nature. However, they do occasionally see battle (albeit usually only in truly dire circumstances) and are equipped with a number of unique weapons to destroy the foes of the Emperor with. These include:
>Purgation Fist: Based on the common Dreadnought “Death Fist” close combat weapon. In addition to the standard power field, these weapons are fitted with various pipes and nozzles that enable the fist to be wreathed in cleansing holy flame. In addition to the obvious psychological effect of a burning hand of vengeance, the Purgation Fist's blessed promethium and potent anti-armour capabilities make it a particularly suitable weapon for dealing with larger daemonic targets, especially daemon engines.
>Chastisement Flail: Similar to the flails used on Penitent Engines, these weapons are relatively simple, consisting of heavy weights attached to lengths of chain. They are brutally effective against most infantry and can make short work of light vehicles, though against heavy armour they struggle. They do not utilize power fields due to the risk of self-inflicted damage that this would cause.
>Holy Censer: A simple weapon consisting of a large censer on a retractable length of chain, filled with blessed incense. Particularly effective against the Chaotic, especially daemons and psykers.
>Indictor Spear: Functioning much like a piledriver, this weapon utilizes a hydraulic ram-driven spike, surrounded by a power field. Whilst clumsy to use even by Dreadnought standards, it is fearsome against armour.
>Condemnor Cannon: A repeating auto-ballista that launches blessed javelins at long range, the projectiles being especially effective against psykers.
Setheno Heavy Tank:
The tank's design is very much emphasised for defence and durability. Its armour is extremely thick, and proof against a great deal of anti-tank weaponry. This does render it very slow, however, though at the very least the engine is far more reliable than the Malcador. The Setheno is generally armed with an Eradicator nova cannon in the hull, whilst the turret and sponsons are outfitted from a selection of plasma cannons, lascannons, assault cannons and heavy flamers in any combination. This makes it one of the few Sororitas vehicles to not adhere to the “holy trinity” of weapons, in part as it was not originally intended for them.
Unfortunately, whilst extremely tough and relatively well armed, the Setheno is not an especially versatile vehicle. Its low speed and high fuel consumption leave it unsuited to long-distance operations, and its weapon layout is often considered obsolete. As such, most of them are used for ceremonial purposes or for defensive operations on shrine worlds. This is not to say they are without merit; during the defence of the world of Belicula III from Hive Fleet Orcus the tanks proved their worth, and were instrumental in repelling the Tyranids. Those Battle Sisters that crew them are generally very fond of the vehicles, and they are treated with the same respect as any other weapon in the Sororitas' arsenals.
Setheno “Purifier” missile tank:
Setheno “Dominator” assault gun:
Rumbler Light Tank:
In theory this makes it an excellent point defence vehicle, though in practice it was found that the far more widely accepted Immolator was superior, as the auto-targeting on the Rumbler's turrets can be unreliable, and the sheer amount of armaments on a relatively small chassis means it quickly runs out of ammunition.
Some Orders still make use of them, however, as they are cheaper and easier to maintain than the Immolator, and the sheer amount of firepower they bring in such a small package is impressive. The heavy bolter and heavy flamer variants are generally more popular than the multi-melta version, though some field conversions replace one of the turrets with a multi-melta.
Curiously, they are alarmingly common in the caches of the few fallen Orders, possibly due to their lower upkeep requirements.
