The T’au Empire is a dynamic rising force in the galaxy, as yet unburdened by the bloody failures of a long history. United by their shared vision of the Greater Good, the T’au strive to bring enlightenment to other races, even if they must do so at the barrel of a gun.

The Hunter Cadres battle for the betterment of the T’au Empire, not for personal gain or egotistic accomplishments. This burning commitment allows for prodigiously effective covering fire. Enemies are pinned in place by deadly bursts of pulse blasts, or the infamous T’au markerlight is used to expose even well-fortified enemy positions, allowing other T’au warriors to fall on the vulnerable enemies with murderous force.
If your Army Faction is T’AU EMPIRE, at the start of your Shooting phase you can select units from your army with this ability to become Observer units.The T'au Empire demands territory. Your priority must be to seize and hold ground. Gouge a foothold for the Fire caste to exploit.
1DPCombining their fire, the Sudden Dawn Cadre prioritise the elimination of a single target before moving on to the next.
(Once per battle, per army) When a friendly SUDDEN DAWN CADRE unit is selected to shoot, you can use this ability. If you do, select one enemy unit. Friendly SUDDEN DAWN CADRE units’ attacks that target that enemy unit have +1 AP until the end of the battle.Proximity ScannersUPGRADE Fitted with hypersensitive scanning devices, this vehicle feeds targeting data to its passengers, allowing them to rapidly bring their pulse weapons to bear and lay down withering fields of fire from the moment of debarkation. SUDDEN DAWN CADRE DEVILFISH unit only. When a friendly unit embarked within this unit disembarks, that friendly unit’s pulse blaster and pulse carbine weapons have +1 A. |

| Q: | When checking line of sight from one model to another, is this drawn between the bases of those models, or between any part of them? |
| A: | Line of sight is drawn from any part of the observing model to any part of the model being observed. |
| Q: | Are models that are within the boundary of a terrain area, but not on the ground floor of a terrain area (e.g. overhanging parts of FRAME VEHICLES or models on terrain features that are within that terrain area) within that terrain area? |
| A: | Yes |
| Q: | When my unit shoots at another unit, how does it work if some models in the target unit are fully visible to some models in my unit, while others are within a terrain area/not fully visible? |
| A: | For each attacking model in your unit, determine whether the target unit has the benefit of cover, as described in Terrain and Visibility. In this scenario, the target unit will likely have the benefit of cover against some of the attacking models, but not all. This means that, in an example unit where all attacking models are using the same weapon, when you get to the Resolve Attacks step of the Attack Sequence, you will collect dice for attacks made by models against which the target unit has the benefit of cover separately from the dice for attacks made by models against which the target unit does not have the benefit of cover. |
The stealthiest warriors can evade the attentions, and the bullets, of their foes.
If every model in a unit has this ability, each time a ranged attack targets that unit, that unit has the benefit of cover against that attack (13.08).Some weapons are designed to root enemy formations out of entrenched positions.
Each time an attack is made with an [IGNORES COVER] weapon, the target cannot have the benefit of cover against that attack (13.08), including from rules that give a model or unit the benefit of cover (e.g. Stealth).
| Q: | Does my model or unit become engaged while moving through a enemy units engagement range during a move? |
| A: | No |
Weapons powered by unstable and dangerous energy sources pose a substantial risk to the wielder and those that stand beside them.
Each time a unit is selected to shoot or selected to fight, after that unit has resolved all of its attacks, make a number of hazard rolls (06.03) for that unit equal to the number of [HAZARDOUS] weapons you selected in the Select Weapons step.
|
| Q: | I have a rule that triggers when a mortal wound is allocated to a model, when does this happen? |
| A: | When you select a model in the Select Model step of Mortal Wounds (06.02). |
| Q: | I failed hazard rolls from [Hazardous] weapons, do those mortal wounds have to be allocated to the models with the [HAZARDOUS] weapons? |
| A: | No, you allocate the mortal wounds to the unit as per Mortal Wounds (06.02). (This represents Bob the guardsmen picking up his fallen squad mates plasma gun or that the twisting power of James the Chaos Sorcerer pulling his followers into the warp.) |
| Q: | If a rule says my unit must make a hazard roll does every model in the unit make a hazard roll? |
| A: | No, the unit would make 1 single hazard roll. |
| Q: | If a unit makes any disembark move in a turn (i.e. Disembark move, Emergency Disembark move etc.) has it disembarked that turn? |
| A: | Yes. |
Many deadly weapons can inflict fatal injuries on any foe, no matter their resilience.
Each time an attack made with a [LETHAL HITS] weapon results in a critical hit, you can choose for that attack to automatically wound the target.
|
| Q: | My attack has a rule that means it results in a critical hit on a hit roll of 4+. Does this work when snap shooting? |
| A: | Unless otherwise stated, no: when snap shooting, each attack only hits on a roll of 6. |
| Q: | My attack has a rule that means it results in a critical hit on a hit roll of 4+, and I would otherwise need a 5+ to hit. Does a 4+ hit? |
| A: | Yes, except when snap shooting: when snap shooting, each attack only hits on a roll of 6. |
The SUDDEN DAWN CADRE and INFANTRY keywords are used in the following Sudden Dawn Cadre datasheets:
| Q: | Is being within range of a terrain objective the same as being within range of an objective marker? |
| A: | Yes. |
| Q: | If my unit has taken control of an objective at the end of my movement phase and that unit has as an ability that secures an objective they control, can they secure that objective? |
| A: | Yes |
Some weapons are so rare, or so complex and slow to reload, that they can only be used once.
Each weapon with this ability can only be selected to make attacks with once per battle.Some transports have dedicated platforms or firing ports from which embarked passengers can lay down a withering hail of munitions.
This ability always takes the form Firing Deck X. In your Shooting phase, each time this TRANSPORT is selected to shoot, if one or more units are embarked within it, resolve the following sequence:| Q: | Do a unit's abilities continue to function while they are embarked within a TRANSPORT? |
| A: | Yes, within the restrictions specified by the ability itself. Embarked units are Not On The Battlefield (01.02.04), so any ability requiring visibility or measurement to another unit will fail. Example: %000035347Azrael% is attached to an Intercessor Squad unit and embarked within a TRANSPORT, and that TRANSPORT is making a shooting attack using the Firing Deck ability. While Azrael’s Supreme Grand Master ability is still technically active, it will have no effect, as the requirements of the ability are not met (the ability affects ‘weapons equipped by models’ in Azrael’s unit, and for the purposes of Firing Deck, the TRANSPORT itself is equipped with those weapons instead). |

The Hunter Cadres battle for the betterment of the T’au Empire, not for personal gain or egotistic accomplishments. This burning commitment allows for prodigiously effective covering fire. Enemies are pinned in place by deadly bursts of pulse blasts, or the infamous T’au markerlight is used to expose even well-fortified enemy positions, allowing other T’au warriors to fall on the vulnerable enemies with murderous force.
If your Army Faction is T’AU EMPIRE, at the start of your Shooting phase you can select units from your army with this ability to become Observer units.High-explosive rounds can fell several warriors in a single blast, but firing them too close to comrades is unwise.
Each time you gather attack dice for a [BLAST] weapon, add one additional attack dice for every five models that were in the target unit in the Select Targets step (rounding down).Indirect fire weapons launch munitions over or around intervening obstacles – nowhere is safe from their fury.
Units containing one or more models with an [INDIRECT FIRE] weapon can shoot using indirect shooting (10.07).| Q: | When declaring the allocation order of groups in my unit I have more than one non-CHARACTER groups that contain a model with a missing wound, how must I select the order? |
| A: | Those groups can be selected in an order of your choosing but must be in an order that makes them come before any non-CHARACTER groups that do not contain a model with a missing wound. |
| Q: | I have a unit being attacked with weapons that will modify some of their save rolls to be worse then 6 should I make those save rolls? |
| A: | Yes, because other models in your unit may have Sv’s that are better those models you’ve mentioned, this means that enough save rolls could be allocated to the those models that the rest of the results are not greater then the Sv’s of the other models in your unit. |
| Q: | Can I group or allocate a wound to a destroyed model? |
| A: | No. |
The most potent weapons strike with such power that they make a mockery of armour and can cleave through several foes.
Each time an attack made with a [DEVASTATING WOUNDS] weapon results in a critical wound, the attack sequence for that attack ends and the target unit suffers a number of mortal wounds equal to the D characteristic of that weapon. These are inflicted after resolving any normal damage inflicted by those attacks.
| ||||||||||||||||||||||||||||||
| Q: | If a unit has a rule that allows it to start an action when it is battle-shocked can it also continue doing that action if it becomes battle-shocked after starting an action? |
| A: | Yes |
| Q: | If a unit becomes battle-shocked after starting an action does it stop performing that action? |
| A: | Yes |
Precision attacks can pick high-value targets out in a crowd.
While resolving attacks made with one or more [PRECISION] weapons, at the start of the Allocation Order step (05.03), if the target unit contains one or more CHARACTER models visible to one or more of the attacking models, the active player can select one allocation group that contains one of those visible CHARACTER models. If they do, until those attacks are resolved, or until that CHARACTER group is destroyed (whichever happens first), that CHARACTER group is the current allocation group.Those possessed of lightning-fast reactions may strike before the opponent can react.
While every model in a unit has this ability, that unit is a Fights First unit.Combining their fire, the Sudden Dawn Cadre prioritise the elimination of a single target before moving on to the next.
(Once per battle, per army) When a friendly SUDDEN DAWN CADRE unit is selected to shoot, you can use this ability. If you do, select one enemy unit. Friendly SUDDEN DAWN CADRE units’ attacks that target that enemy unit have +1 AP until the end of the battle.Enhanced by the artifice of the Earth caste, this Enforcer Battlesuit features enhanced telemetry fire rates, allowing for the effective suppression of enemies and accurate insertion from low orbit.
SUDDEN DAWN CADRE COMMANDER IN ENFORCER BATTLESUIT model only.
Folding stocks, shortened barrels or lightweight construction enable some weapons to be easily fired on the move.
Units containing one or more models with an [ASSAULT] weapon can shoot using assault shooting (10.05).Weapons designed for close-quarters fighting can be wielded effectively even in the press of melee combat.
Units containing one or more models with a [CLOSE-QUARTERS] weapon can shoot using close-quarters shooting (10.06).Dual weapons are often grafted to the same targeting system for greater lethality.
Each time an attack is made with a [TWIN-LINKED] weapon, you can re-roll the wound roll.Fitted with hypersensitive scanning devices, this vehicle feeds targeting data to its passengers, allowing them to rapidly bring their pulse weapons to bear and lay down withering fields of fire from the moment of debarkation.
SUDDEN DAWN CADRE DEVILFISH unit only. When a friendly unit embarked within this unit disembarks, that friendly unit’s pulse blaster and pulse carbine weapons have +1 A.
Heavy weapons are amongst the biggest guns on the battlefield, but require bracing to fire at full effect.
In your Shooting phase, each time an attack is made with a [HEAVY] weapon, add 1 to the hit roll if all of the following apply to the attacking unit:
