While other vehicles can only move in the Movement phase, walkers can also run in the Shooting phase and assault in the Assault phase, just as infantry can.

Walkers move in exactly the same way as infantry, so they can move up to 6" in the Movement phase and assault up to 6" in the Assault phase.

Difficult terrain affects walkers just as it does infantry. Difficult terrain only counts as dangerous terrain for walkers if it would do so for infantry. If walkers fail a dangerous terrain test, they are immobilised.

Unlike infantry, a walker has a facing, which influences where it can fire and its Armour Value when fired at.

Walkers can move and fire all of their weapons, just like a stationary vehicle.

Alternatively, they can choose to run like infantry, and this prevents them from firing and assaulting that turn, as normal (though they can still trigger their smoke launchers, if they have any). Obviously they cannot run if they are stunned or immobilised.

When firing a walker’s weapons, pivot the walker on the spot so that its guns are aimed at the target (assume that all weapons mounted on a walker can swivel 45º, like hull-mounted weapons) and then measure the range from the weapon itself and line of sight from the mounting point of the weapon and along its barrel, as normal for vehicles. This pivoting in the Shooting phase does not count as moving and represents the vastly superior agility of walkers in comparison with other vehicles. Keep in mind however that the walker will probably remain facing in this direction until its next Movement phase, so its facing will determine where its rear armour is going to be when the enemy returns fire!

Walkers that are locked in combat cannot be shot at.

Walkers assault like infantry models, meaning that they make assault moves and can be locked in combat with enemy units. Walkers can make an assault even if they fired heavy or rapid fire weapons. However, like normal infantry, they can still only assault the unit they fired at.

In close combat, walkers fight like infantry models. However, any hits scored against them must roll for armour penetration and damage as for a vehicle. Models hitting a walker in close combat always roll for penetration against its front armour.

Grenades and melta bombs can be used against a walker. A model will only manage to score a hit with a grenade against a walker on the roll of 6. However, if a walker is already stunned or immobilised at the start of the Assault phase, the attackers roll to hit based on the normal comparison of WS. Remember that models using grenades against vehicles only make one attack.

Immobilised and/or stunned walkers fight in close combat with one less attack than usual (to a minimum of 1), but otherwise attack normally, no matter how many immobilised and stunned results they suffered.

Shaken damage results do not affect the way a walker fights in close combat.

Each roll made on the Vehicle Damage table against a walker counts as a single wound for the purposes of working out who won the combat.

Defeated walkers do not take Morale checks and are not affected by the No Retreat! rule.

Walkers make sweeping advances, pile-in moves and consolidations unless they are stunned or immobilised.

If a walker is rammed by a tank, it can choose to either brace itself for the impact, in which case the collision is resolved as normal for a vehicle, or it can attempt a ‘Death or Glory!’ attack in the same way as infantry (it cannot do this, however, if it is rammed in its rear arc).

If it chooses ‘Death or Glory!’ and its attack fails to stop the ramming tank, the walker will not be ready for the impact and is hit on its rear armour in the collision.

Profiles:

Abilities
Reinforced Aegis: Psychic test Leadership penalties caused by The Aegis are increased to -4 if the target of the psychic power is within 12" of the Dreadnought (or is the Dreatnought itself).
Venerable: If a Venerable Dreadnought suffers a glancing or penetrating hit, you can ask your opponent to re-roll the result rolled on the Vehicle Damage Chart. You must accept the result of the second roll, even if its worse than the first.
The Aegis: If an enemy Psyker attempts to target a model with the Aegis special rule (or a unit that contains a model with the Aegis special rule) he suffers a -1 Penalty to his Leadership for the purposes of his Psychic test. A psychic power that does not specifically target a unit with the Aegis special rule does not suffer this penalty, even if the unit with the Aegis special rule is affected by the psychic power.
Preffered Enemy (Daemons): Units with this ability can always re-roll their rolls to hit in close combat against Daemons. This ability does not work when attacking vehicles without a Weapon Skill characteristic.
Psychic Pilot: A vehicle with this special rule is treated as being a Psyker (Mastery level 1) and Leadership 10 for the purposes of Psychic tests and Psychic Hoods. If the vehicle suffers the Perils of the Warp, treat it as a glancing hit.

Psychic Power
Fortitude: This power can be used in the Grey Knight's Movement phase. If the Psychic test is successful, any crew shaken and crew stunned results already on the vehicle are nullified and no longer apply.

Wargear
Smoke Launchers: Once per game, after completing its move, a vehicle with smoke launchers can trigger them (it doesn’t matter how far it moved). Place some cotton wool or other suitable marker on or around the vehicle to show it is obscured. The vehicle may not fire any of its weapons in the same turn as it used its smoke launchers, but will count as obscured in the next enemy Shooting phase, receiving a 4+ cover save. After the enemy’s Shooting phase, the smoke disperses with no further effect. Note that a vehicle may still use smoke launchers even if its crew are shaken or stunned. It is worth pointing out that some armies might use different versions of smoke launchers, which have slightly different rules. As normal, the rules in the Codex take precedence.
