Archaeopter Transvector

Some AIRCRAFT models have 'Hover' listed in their abilities. When you are instructed to Declare Battle Formations, before doing anything else, you must first declare which models from your army with this ability will be in Hover mode.

If a model is in Hover mode,  then until the end of the battle, its Move characteristic is changed to 20", it loses the AIRCRAFT keyword and it loses all associated rules for being an AlRCRAFT model. Models in Hover mode do not start the battle in Reserves, but you can choose to place them into Strategic Reserves following the normal rules if you wish.

During the Declare Battle Formations step, if every model in a unit has this ability, you can set it up in Reserves instead of setting it up on the battlefield. If you do, in the Reinforcements step of one of your Movement phases you can set up this unit anywhere on the battlefield that is more than 9" horizontally away from all enemy models.

If a unit with the Deep Strike ability arrives from Strategic Reserves, the controlling player can choose for that unit to be set up either using the rules for Strategic Reserves or using the Deep Strike ability.

Some models have 'Deadly Demise x' listed in their abilities. When such a model is destroyed, roll one D6 before removing it from play (if such a model is a TRANSPORT, roll before any embarked models disembark). On a 6, each unit within 6" of that model suffers a number of mortal wounds denoted by 'x' (if this is a random number, roll separately for each unit within 6").

At the start of the battle round, you can select one of the Doctrina Imperatives below. Until the end of the battle round, that Doctrina Imperative is active for your army, and all units from your army that have the Doctrina Imperatives ability gain the relevant abilities shown below.

PROTECTOR IMPERATIVE

■ Each time a melee attack targets this unit, if this unit has the Battleline keyword and/or it is within 6" of one or more friendly Adeptus Mechanicus Battleline units, subtract 1 from the Hit roll.

CONQUEROR IMPERATIVE
■ Ranged weapons equipped by models in this unit have the [ASSAULT] ability.
■ Improve the Weapon Skill characteristic of melee weapons equipped by models in this unit by 1.
■ Each time a model in this unit makes an attack, if this unit has the Battleline keyword and/or it is within 6" of one or more friendly Adeptus Mechanicus Battleline units, improve the Armour Penetration characteristic of that attack by 1.
