Kauyon
The Kauyon Detachment for the T’au Empire reflects a strategic approach emphasizing patience and precision, suitable for players who prefer to set traps and ambush their opponents.
The ‘Patient Hunter’ detachment rule encapsulates this ethos, rewarding players who position and time their strikes carefully, with enhanced hitting and wounding capabilities beginning from the third battle round.
The detachment offers an array of stratagems that synergize with this patient and strategic playstyle. ‘A Tempting Trap’ provides a bonus to wound rolls near a chosen objective, incentivizing careful positioning.
‘Point-blank Ambush’ rewards close-range engagements with improved armour penetration, while ‘Coordinate to Engage’ enhances the accuracy and effectiveness of Observer units against designated targets.

‘Combat Embarkation’ and ‘Photon Grenades’ offer tactical options to mitigate enemy charges, and ‘Wall of Mirrors’ provides a strategic retreat to preserve key units.
Kauyon enhancements boost this tactical framework. ‘Exemplar of the Kauyon’ allows units to benefit from the ‘Patient Hunter’ rule a round earlier, ‘Precision of the Patient Hunter’ grants cumulative bonuses to hit and wound as the battle progresses, ‘Solid-image Projection Unit’ offers unparalleled redeployment flexibility, and ‘Through Unity, Devastation’ leverages Observer units to deliver potentially game-changing lethal hits.
Kauyon Detachment Rule: Patient Hunter
Starting with the third battle round, T’au Empire models from your army equipped with ranged weapons gain the [SUSTAINED HITS 1] ability, or the [SUSTAINED FIRE 2] ability when targeting their unit’s Spotted unit.
Stratagems available for the Kauyon Detachment:
- A Tempting Trap (1CP) – Battle Tactic Stratagem: During your Shooting phase, select one T’AU EMPIRE unit from your army that hasn’t shot yet this phase. The first time you use this Stratagem, also choose one objective marker outside your opponent’s deployment zone to be your Trap objective marker for the remainder of the battle. Until the end of the phase, any model in your selected unit gets a +1 bonus to the Wound roll when making a ranged attack against any enemy unit near your Trap objective marker. Note that this Stratagem cannot be used during the first or second battle rounds.
- Point-blank Ambush (1CP) – Battle Tactic Stratagem: During your Shooting phase, choose a T’AU EMPIRE unit from your army that has not yet shot in this phase. For the duration of the phase, whenever a model from this unit makes a ranged attack targeting an enemy unit within 9 inches, the Armour Penetration characteristic of that attack is increased by 1. This Stratagem cannot be used during the first or second battle rounds.
- Coordinate to Engage (1CP) – Battle Tactic Stratagem: During your Shooting phase, select one T’AU EMPIRE unit from your army that has just been designated as an Observer unit (as outlined in “For the Greater Good”). For the rest of the phase, whenever a model from this unit attacks their Spotted unit, the Ballistic Skill characteristic of that attack improves by 1. Additionally, if your unit is marked with the MARKERLIGHT keyword, that attack gains the (IGNORES COVER) ability.
- Combat Embarkation (1CP) – Wargear Stratagem: During your opponent’s Charge phase, right after an enemy unit declares a charge, target one T’AU EMPIRE INFANTRY unit from your army that was chosen as a charge target and one friendly TRANSPORT. The targeted INFANTRY unit can then embark into the TRANSPORT. However, every model in the INFANTRY unit must be within 3 inches of the TRANSPORT, and there must be enough space in the TRANSPORT to accommodate the entire unit.
- Photon Grenades (1CP) – Wargear Stratagem: During your opponent’s Charge phase, immediately after an enemy unit has declared a charge, you can target one T’AU EMPIRE GRENADES unit from your army that was chosen as one of the charge targets. The enemy unit must then take a Battle-shock test right away. Additionally, until the end of the phase, subtract 2 from any Charge rolls made by that enemy unit. This action cannot be taken if your targeted unit is within Engagement Range of one or more enemy units.
- Wall of Mirrors (1CP) – Battle Tactic Stratagem: At the end of your opponent’s Fight phase, you can select one STEALTH, GHOSTKEEL, or COMMANDER SHADOWSUN unit from your army. Remove this unit from the battlefield and place it into Strategic Reserves. This action cannot be taken if the unit you wish to target is within Engagement Range of one or more enemy units.
Kauyon Enhancements:
- Exemplar of the Kauyon (+20 points): For T’AU EMPIRE models (except KROOT SHAPER models). When the bearer leads a unit, the Patient Hunter Detachment rule starts in the second battle round, not the third.

When the bearer leads a unit, and the unit is an Observer unit, until the end of the phase, ranged weapons held by models in their Guided unit gain the [LETHAL HITS] ability when targeting their Spotted unit.
Mont’ka
The Mont’ka Detachment is the embodiment of the T’au Empire’s doctrine of the rapid and decisive strike. This detachment is designed for players who favor an aggressive and dynamic playstyle, focusing on delivering powerful ranged attacks early in the battle.
The ‘Killing Blow’ detachment rule grants the [LETHAL HIT] ability to ranged weapons in the first three battle rounds, emphasizing the Mont’ka’s philosophy of delivering a swift and deadly attack to overwhelm the enemy. The addition of the [ASSAULT] ability to units designated as Guided enhances the mobility and flexibility of T’au firepower.
Stratagems associated with the Mont’ka Detachment further bolster this hit-and-run tactic. ‘Pinpoint Counter-offensive’ allows for vengeance-fueled re-rolls on hit rolls against the unit that destroyed a T’au unit, adding a retaliatory edge to engagements. ‘Aggressive Mobility’ ensures maximum movement during the Advance, facilitating rapid redeployment.

‘Focused Fire’ improves the armour penetration against a designated enemy unit, consolidating firepower for maximum impact. ‘Combat Debarkation’ and ‘Pulse Onslaught’ leverage the shock of Tau infantry actions, while ‘Counterfire Defence Systems’ provide a measure of damage mitigation during enemy shooting phases.
Mont’ka enhancements are tailored to maximize the doctrine’s impact in the early to mid-game. ‘Exemplar of the Mont’ka’ extends the Killing Blow rule’s effectiveness to the fourth battle round, ‘Strike Swiftly’ provides an initial positioning advantage, ‘Strategic Conqueror’ strengthens objective control, and ‘Coordinated Exploitation’ increases the lethality of Observer units’ guided allies.
Mont’ka Detachment Rule: Killing Blow

- Pinpoint Counter-offensive (1CP) – Battle Tactic Stratagem: During any phase, you can use this Stratagem on a TAU EMPIRE unit (excluding KROOT units) from your army immediately after it has been destroyed. For the rest of the battle, whenever a T’AU EMPIRE unit (excluding KROOT units) from your army attacks the enemy unit responsible for destroying your unit, you are allowed to re-roll the Hit roll.
- Aggressive Mobility (1CP) – Battle Tactic Stratagem: During your Movement phase, target one T’AU EMPIRE unit from your army that has not yet moved. If this unit chooses to Advance during the phase, skip the Advance roll. Instead, simply add 6 inches to the Move characteristic of the models in your unit for the duration of the phase.
- Focused Fire (1CP) – Battle Tactic Stratagem: At the start of your Shooting phase, select two T’AU EMPIRE units from your army that have not yet been chosen to shoot, and one enemy unit. Throughout the phase, models in your selected units can only attack the chosen enemy unit, provided it is a valid target for those attacks. Additionally, the Armour Penetration characteristic of these attacks is improved by 1. This Stratagem cannot be used during the fourth or fifth battle rounds.
- Combat Debarkation (1CP) – Battle Tactic Stratagem: During your Shooting phase, target one T’AU EMPIRE INFANTRY unit from your army that disembarked from a TRANSPORT this turn. For the remainder of the phase, each time a model in this unit makes an attack targeting the closest enemy unit, you are allowed to re-roll the Wound roll.
- Pulse Onslaught (2CP) – Strategic Ploy Stratagem: During your Shooting phase, select one T’AU EMPIRE INFANTRY unit (excluding KROOT units) from your army that has just shot, along with one enemy unit (excluding MONSTERS and VEHICLES) that was hit by one or more attacks from your unit. Until the end of your opponent’s next turn, the targeted enemy unit is considered shaken. While shaken, the enemy unit’s Move characteristic is reduced by 2, and it must subtract 2 from any Advance and Charge rolls.
- Counterfire Defence Systems (2CP) – Wargear Stratagem: During your opponent’s Shooting phase, immediately after an enemy unit has chosen its targets, select one T’AU EMPIRE unit from your army that has been targeted by one or more of the enemy’s attacks. For the remainder of the phase, whenever an attack is allocated to your selected unit, reduce the Damage characteristic of that attack by 1.
Mont’ka Enhancements:
- Exemplar of the Mont’ka (+10 points): For T’AU EMPIRE models only (excluding KROOT SHAPER models). When the bearer is leading a unit, the Killing Blow Detachment rule also becomes effective for that unit during the fourth battle round.

For the duration of the battle, all models in these selected units gain the Scouts 6″ ability.
- Strategic Conqueror (+15 points): For T’AU EMPIRE models only. At the start of the first battle round, before the first turn begins, select one objective marker on the battlefield.

Retaliation Cadre
The Retaliation Cadre Detachment for the T’au Empire in the Warhammer 40K game is a specialized formation geared towards enhancing the offensive capabilities of Battlesuit units.
Central to this detachment is the ‘Bonded Heroes’ rule, which bolsters the strength and armor penetration of Battlesuit models’ ranged attacks, depending on their proximity to the target. This encourages players to position their Battlesuits aggressively to maximize their offensive output.
Several stratagems unique to the Retaliation Cadre Detachment offer tactical versatility. ‘Fail-safe Detonator’ allows a player to ensure a model’s destructive final act upon destruction, ‘Stimm Injectors’ provide a damage mitigation chance, and ‘The Shortened Blade’ grants deep strike flexibility.

‘The Arro’kon Protocol’ increases the effectiveness against large enemy units, while ‘The Torchstar Gambit’ adds mobility after shooting. Defensive strategies are enhanced with ‘Grav-inhibitor Field,’ potentially disrupting enemy charges.
Enhancements such as the ‘Puretide Engram Neurochip’ allow for stratagem reuse on a unit, ‘Starflare Ignition System’ offers strategic redeployment, ‘Internal Grenade Racks’ give a direct damage option after movement, and ‘Prototype Weapon System’ adds versatility to the unit’s shooting phase.
Retaliation Cadre Detachment Rule: Bonded Heroes

Stratagems available for the Retaliation Cadre Detachment:
- Fail-safe Detonator (2CP)– Epic Deed Stratagem: During any phase, right after a T’AU EMPIRE BATTLESUIT model from your army is destroyed, you can use this Stratagem on the unit of the destroyed model, even if the entire unit was just destroyed. Before removing the model from play, if it has the Deadly Demise ability, you do not need to roll for it; instead, you can decide whether the outcome of that roll is a 1 or a 6.
