Cataphractii Terminators Guide — Ancient Armor Tactics

What Are Cataphractii Terminators?

Cataphractii Terminators wear the oldest and heaviest pattern of Tactical Dreadnought Armour, a design that dates back to the Great Crusade. Where the later Indomitus pattern balances protection with mobility, Cataphractii armour gives up agility for maximum survivability. The result is a warrior so heavily armoured that he moves at a ponderous pace but can shrug off firepower that would kill lighter-armoured Space Marines outright.

During the Horus Heresy, Cataphractii armour was the premier close-quarters armour available to the Space Marine Legions. It was the armour of choice for boarding actions against enemy warships, breaching assaults on fortress walls and any fight where the enemy’s firepower would be concentrated into a killing zone. Cataphractii-clad Terminators would advance into the teeth of the enemy’s best weapons, absorb everything thrown at them and reach the enemy line with enough warriors standing to win the melee that followed.

In the 41st Millennium, Cataphractii armour is a relic: each suit a priceless artefact maintained by Chapter artificers and Techmarines who may not fully understand its ancient mechanisms. Only the most veteran Terminators are honoured with a suit of Cataphractii plate, and committing them to battle is never done lightly. The pattern also survives among the Traitor Legions, most famously as the corrupted armour of the Death Guard’s Blightlord and Deathshroud Terminators.

Do Cataphractii Terminators Have a 40k Datasheet?

This is the first thing to check before you buy or build. The plastic Cataphractii Terminator Squad is part of the Warhammer: The Horus Heresy range, and Cataphractii Terminators are not part of the main unit range in the current Space Marines codex. In recent editions, Heresy-pattern Terminators have only been supported in Warhammer 40,000 through Warhammer Legends rules, which are meant for casual and narrative games rather than matched play.

That leaves you three practical options in 11th Edition:

Use them as standard Terminators. This is the most common choice. The models are a natural stand-in for a Terminator Squad, as long as their weapons roughly match the datasheet you’re using and your opponent knows what they represent.
Use a Legends datasheet, if one is available, in casual or narrative games where your group agrees to Legends units.
Play Warhammer: The Horus Heresy, where Cataphractii are a fully supported core unit of every Legion.

Rules availability changes over time, so check the Warhammer 40,000 app, the current Space Marines codex and the Munitorum Field Manual for what is legal and how many points it costs before writing a list.

Weapon Loadouts

The Cataphractii kit is built with Heresy-era weapons that overlap with, but are not identical to, standard Terminator options. Which of these you can actually use in 40k depends on the datasheet you’re playing them as, so check it before gluing weapons on.

Combi-bolter and Power Fist

The classic loadout: ranged fire from the combi-bolter and strong melee from the power fist. It’s the all-purpose configuration, and it maps neatly onto a standard Terminator Squad’s storm bolters and power fists.

Lightning Claws

Paired lightning claws give up ranged weapons for a flurry of melee attacks, making them the best choice against infantry. Without guns, these models contribute nothing while closing the distance, so plan how they’ll get into combat.

Thunder Hammer and Storm Shield (Conversion)

The plastic Cataphractii kit doesn’t include thunder hammers or storm shields, so this loadout needs parts from another kit. It’s worth the effort if you’re representing Assault Terminators: the thunder hammer hits harder per blow than any other Terminator melee weapon, and the storm shield adds extra protection, at the cost of fewer attacks.

Heavy Weapons

The plastic kit includes heavy flamers; Heresy rules also allow other heavy weapons such as the reaper autocannon, and you can add an assault cannon from another kit if you’re representing a standard Terminator Squad. They add ranged threat but don’t change the unit’s identity as a close-quarters force.

How to Use Cataphractii (and Terminators) in 11th Edition

Whether you field your Cataphractii as standard Terminators or with a Legends datasheet, the same 11th Edition core rules shape how you get them into the fight.

Deep Strike

Terminators are slow on foot, so Deep Strike is the usual way to deliver them. In 11th Edition, Deep Strike units go into strategic reserves (which can’t exceed half your points), can’t arrive in battle round 1, and must set up more than 8″ horizontally from all enemy units. Anything still in reserve at the end of battle round 3 is destroyed, so plan to land in round 2 or 3.

A unit that arrives this way can still shoot and declare a charge that turn, but it can’t make any other move until the Charge phase. Because engagement range is now 2″, you need a 7 or more on 2D6 to make the charge from just over 8″ away, which is better odds than the old 9″ charge but still far from certain. The core Rapid Ingress Stratagem lets you bring them in at the end of your opponent’s Movement phase instead. For the full rules, see our Deep Strike guide.

Transport Delivery

Land Raiders can carry Terminators, advancing them to the front line while providing fire support, then letting them out within charge range. This is more reliable than a deep strike charge and lets the squad contribute from turn one through the transport’s weapons, but it adds a big points investment in the Land Raider itself.

Objective Holding

Terminators are excellent at holding objectives through sheer durability. In 11th Edition, objectives are terrain areas, and a unit only needs to be inside that area to control it. Drop a Terminator squad onto a midfield objective and dare your opponent to shift it.

Will it actually kill that? Run the hit / wound / save odds with the dice calculator.

Anvil Units

In a combined-arms army, heavy Terminators make a perfect anvil: the immovable force that holds the enemy in place while faster units (Assault Intercessors, Vanguard Veterans, bikes) move in for the killing blow.

Character Attachments

In 11th Edition, Leader and Support characters are attached to their bodyguard unit when you write your army roster, and each bodyguard unit can take one Leader and one Support. Characters in Terminator armour, such as a Captain, Librarian or Chaplain in Terminator armour, are the natural fit for a Terminator squad. Which characters can join which unit is listed on each character’s datasheet, and the Munitorum Field Manual takes priority if the two disagree.

Two rules matter most here. First, Deep Strike only works if every model in the unit has it, so make sure your attached character can Deep Strike too. Second, while any bodyguard models are alive, attacks go to them before the characters, unless the attacker uses Precision weapons. See our guide to Leader rules in 11th Edition for details.

Cataphractii vs Indomitus vs Tartaros

There are three well-known patterns of Terminator armour, and knowing them helps with both lore and modelling:

Cataphractii: The oldest and heaviest pattern, with bulky pteruges and massive shoulder plates. Built for maximum protection at the cost of mobility.
Tartaros: A lighter, more agile Heresy-era pattern, faster and more manoeuvrable than Cataphractii.
Indomitus: The standard pattern of the 41st Millennium and the one used by the current Space Marine Terminator kits, balancing protection and mobility.

In Horus Heresy games the patterns have distinct rules. In 40k, the main rules question is which datasheet you’re representing them with.

Frequently Asked Questions

Are Cataphractii Terminators worth taking?

As models, absolutely: they’re among the most characterful Terminators GW makes. For 40k matched play, they’re usually fielded as standard Terminators, since they aren’t part of the current Space Marines codex range. If you want their full Heresy-era rules, they shine in Warhammer: The Horus Heresy, where they’re the toughest Terminators available.

What is the best Cataphractii loadout?

Combi-bolter and power fist is the versatile default, and the one the kit is built around. Lightning claws are best against infantry. Thunder hammer and storm shield gives the best mix of durability and damage, but those parts don’t come in the plastic Cataphractii kit. If you plan to use them as 40k Terminators, match the loadout to the datasheet you’ll field them as.

Can Cataphractii Terminators fit in a Land Raider?

Yes. Land Raiders can transport Terminator-armoured models, and a squad of five plus an attached character is the classic Land Raider load. Check the transport capacity on the Land Raider’s current datasheet before planning around it.

How do Cataphractii compare to Bladeguard Veterans?

Both are durable melee infantry. Bladeguard Veterans are a current Space Marines codex unit, faster on foot and built around master-crafted swords and storm shields. Terminators are tougher and hit harder but are slower and more expensive. Choose based on whether you need staying power or mobility, and remember that Bladeguard have full matched play support.

Are Cataphractii Terminators available in competitive play?

Not as their own unit in the current Space Marines codex. In recent editions, Heresy-era Terminator patterns have been limited to Warhammer Legends, which isn’t used in matched play. Most competitive players use the models as standard Terminators where the event allows it. Always check the latest rules and your event’s model policy.

Which kit makes Cataphractii Terminators?

The plastic Cataphractii Terminator Squad from the Warhammer: The Horus Heresy range. The Legion-era models are designed for Horus Heresy games, but plenty of players use them in Warhammer 40,000 too, either with their own datasheet where one exists or as standard Terminators. Check the current Space Marines rules in the app before building a list.

Can I use Cataphractii models as normal Terminators?

Usually yes, in casual games, as long as your opponent knows what they represent and the weapons roughly match. The bulky armour and similar base size make them a natural stand-in. At events, check the organiser’s policy on models that don’t exactly match the datasheet you’re using.
