Repulsor Executioner Guide — Space Marine Heavy Tank

The Emperor’s Armoured Fist — Repulsor Executioner Overview

The Repulsor Executioner is one of the most powerful vehicles available to Space Marine armies in Warhammer 40,000. Built upon the chassis of the standard Repulsor transport, the Executioner variant sacrifices some of its transport capacity to mount a devastating primary weapon system — either the heavy laser destroyer or the macro plasma incinerator. The result is a main battle tank that can annihilate enemy armour while still carrying a small contingent of Primaris Space Marines into the fight.

The Repulsor Executioner represents the pinnacle of Primaris vehicle technology. Designed by Archmagos Dominus Belisarius Cawl during his ten-thousand-year project to create the next generation of Space Marines and their equipment, the Executioner combines anti-gravity propulsion, heavy armour, and enough firepower to level a city block. It is the Imperium’s answer to the question: “What if we put an even bigger gun on it?”

In lore, the Repulsor Executioner is deployed when Space Marine forces need overwhelming armoured firepower. It has been used to crack open fortified positions, duel enemy super-heavy vehicles, and provide devastating fire support during planetary assaults. Its anti-gravity drives allow it to traverse terrain that would stop tracked vehicles dead, giving it excellent tactical mobility despite its immense size and weight.

Repulsor Executioner Datasheet Breakdown

The Repulsor Executioner is a heavy vehicle with an impressive statline. It features high Toughness and a strong Save characteristic, making it genuinely durable against all but the most dedicated anti-tank firepower. Its Wounds pool is substantial, meaning it can absorb significant punishment before being destroyed.

Movement is respectable for a vehicle of its size, thanks to the anti-gravity drives. It does not suffer penalties for moving and firing heavy weapons, which is critical for a vehicle that wants to be repositioning while laying down devastating fire every turn.

The main weapon is the star of the show. The heavy laser destroyer delivers incredibly high Strength, high AP, high Damage shots that can cripple or destroy enemy vehicles in a single volley. Alternatively, the macro plasma incinerator offers a blast profile that is devastating against elite infantry and lighter vehicles, with the option to overcharge for even more power at the risk of taking mortal wounds.

On top of the main weapon, the Executioner bristles with secondary armament. Twin heavy bolters, an ironhail heavy stubber, twin fragstorm grenade launchers, and an Icarus rocket pod for anti-air capability mean that this tank is never short of targets it can engage. The sheer volume of secondary fire makes it effective against infantry swarms that might otherwise try to swamp it.

Heavy Laser Destroyer vs Macro Plasma Incinerator

This is the key decision when building your Repulsor Executioner, and the answer depends on your local meta and army composition.

Heavy Laser Destroyer

The heavy laser destroyer is the dedicated anti-tank option. It fires fewer shots but at extreme Strength with high AP and high Damage per shot. This makes it exceptional against enemy vehicles, monsters, and other high-Toughness targets. If your meta is dominated by Knights, Leman Russ tanks, or other heavy armour, the laser destroyer is your best bet. Its main weakness is overkill — those massive damage numbers are wasted when shooting at infantry.

Macro Plasma Incinerator

The macro plasma incinerator offers more versatility. It fires more shots at a slightly lower Strength and Damage profile, but with the Blast keyword, it gets bonus shots against larger units. This makes it more flexible, as it can threaten both vehicles and elite infantry effectively. The overcharge option adds risk but significantly increases its killing power. If you face a varied meta with both vehicles and elite infantry, the macro plasma is often the better choice.

The Verdict

In most competitive environments, the heavy laser destroyer edges ahead because dedicated anti-tank firepower is harder to come by than anti-infantry options. Your other units can handle infantry — the Executioner’s job is to kill the biggest, toughest thing on the other side of the table.

Transport Capacity and Usage

Unlike many dedicated battle tanks, the Repulsor Executioner retains some transport capacity. It can carry a small unit of Primaris infantry, which opens up interesting tactical possibilities.

You can use the transport capacity to deliver a key unit — such as Bladeguard Veterans or a character — to a critical position while the Executioner provides fire support. The passengers disembark, take an objective or charge into melee, while the tank sits back and shoots. This dual-purpose functionality is what separates the Executioner from dedicated tanks that can only shoot.

However, do not overvalue the transport capacity. The Executioner is first and foremost a gun platform, and you should build your list around its firepower, not its ability to carry troops. Consider the transport as a bonus rather than a primary function.

Repulsor Executioner Tactics

Deployment and Positioning

Deploy the Executioner with clear firing lanes to expected enemy armour positions. It wants to start shooting from Turn 1 and never stop. Place it behind terrain that blocks line of sight from enemy anti-tank weapons while allowing it to peek out and fire during your turn. The anti-gravity drives mean it can move over terrain features that would block other vehicles, so use this mobility to find advantageous positions.

Target Priority

Your primary targets should always be enemy vehicles and monsters. The heavy laser destroyer is one of the best anti-tank weapons in the Space Marine arsenal, and wasting it on infantry is almost always wrong. Focus fire on the biggest threat — kill enemy tanks before they kill you. Once enemy armour is neutralised, use secondary weapons to mop up infantry.

Protecting Your Investment

The Executioner is a significant points investment, and losing it early can cripple your army. Screen it with infantry to prevent enemy deep strikers from charging it. Keep it at maximum range when possible — most anti-tank weapons have shorter range than the heavy laser destroyer, so distance is your friend. Use terrain to block line of sight from units that are not your primary target.

Army Synergies

The Repulsor Executioner pairs excellently with units that buff its shooting. A Techmarine can repair damage and potentially improve its ballistic skill. Captains provide re-rolls that are incredibly valuable on high-damage weapons where each hit matters enormously. Consider building a fire support castle with the Executioner at its centre, surrounded by buffing characters.

Repulsor Executioner in Competitive Play

The Repulsor Executioner sees regular competitive play as one of the premier Space Marine anti-tank options. Its combination of devastating firepower, reasonable durability, and transport capacity makes it a versatile choice that can contribute to multiple aspects of your game plan.

In tournament play, the Executioner excels in missions where controlling the centre of the board is important. It can sit in a midfield position, threatening enemy vehicles across the entire table while transporting troops forward to claim objectives. Its secondary weapons ensure it is never truly out of targets, even if the enemy hides their vehicles.

The main competitive weakness is its cost. At its points level, losing the Executioner early is devastating. Skilled opponents will prioritise it, and if they can destroy it in the first two turns, your army loses a massive chunk of its firepower. Always have a backup plan for killing enemy armour in case your Executioner goes down.

Painting Your Repulsor Executioner

The Repulsor Executioner is a large model with a lot of flat armour panels, making it an excellent candidate for weathering and battle damage effects. Base coat in your Chapter colours, then add edge highlighting to define the armour panels. Weathering with sponge-applied damage, streaking grime, and dust effects on the lower hull will make the model look like it has seen real combat. The anti-gravity drives underneath can be painted with a blue or green glow effect to suggest energy.

Frequently Asked Questions

Is the Repulsor Executioner worth its points?

Yes, in lists that need dedicated anti-tank firepower. It is one of the most efficient ways for Space Marines to destroy enemy vehicles. However, it needs to survive and shoot for multiple turns to earn back its investment.

Should I take one or two Repulsor Executioners?

One is standard in most competitive lists. Two is a massive points investment that leaves you thin elsewhere. If you do take two, ensure the rest of your army can handle objectives and screening.

What should I transport in the Executioner?

Small, high-impact units work best. Bladeguard Veterans, a character, or a small Intercessor squad for objective grabbing. Do not waste the transport on large units — use Impulsors or Rhinos for that.

How does it compare to other Space Marine tanks?

The Executioner is the hardest-hitting tank option but also the most expensive. Gladiator Lancers are cheaper anti-tank alternatives, while Predators offer a budget option. The Executioner is the premium choice when you absolutely need something dead.

Can a Repulsor Executioner move and shoot without penalty?

Yes, as a vehicle it does not suffer penalties for moving and shooting heavy weapons, so you can reposition freely while maintaining full firepower.

Is there a Gladiator Executioner in 40k?

No. The Executioner is a variant of the Repulsor, not the Gladiator. The Gladiator tank comes in three versions: the Gladiator Lancer with its anti-tank las-cannon, the Gladiator Reaper with tempest bolters against infantry, and the Gladiator Valiant with multi-meltas and las-talons. If you want the heavy laser destroyer or macro plasma incinerator, you want the Repulsor Executioner.

What is the difference between a Repulsor and a Repulsor Executioner?

The standard Repulsor is mainly a transport, carrying a large Primaris squad and covered in lighter anti-infantry weapons. The Repulsor Executioner gives up most of that transport space for a main battle gun, either a heavy laser destroyer or a macro plasma incinerator. That turns it into a battle tank that can still carry a small unit.
