A Grey Knight unit can use one Psychic power each turn. The unit counts as a single Psyker and follows all the normal rules for Psykers, with the following clarifications:


• A Grey Knight unit uses the Leadership of its Justicar or Knight of the Flame (if he is alive), or the unit (if he is dead) for Psychic tests. A Grey Knight unit can never use the Leadership value of an Independent Character for Psychic tests.


• If the Grey Knight unit suffers the Perils of the Warp, or any attack that specifically targets Psykers, it is resolved against the Justicar or or Knight of the Flame (if he is alive) or against a random non-character model in the squad if the Justicar or Knight of the Flame is dead.

Combat Squads

A number of ten-man units in the Space Marines army have the option of breaking down into two five-man units, called combat squads. The decision to split the unit into combat squads, as well as which models go into each combat squad, must be made when the unit is deployed. Both combat squads can be deployed in separate locations. The one exception to this is a unit that arrives by Drop Pod. The player can choose to split such a unit into combat squads when it disembarks from the Drop Pod.


If you decide to split the unit into combat squads, then each combat squad is treated as a separate unit for all game purposes from that point.

Profiles:

Wargear
Frag Grenades: Models equipped with assault grenades don’t suffer the penalty to their Initiative for assaulting enemies through cover, but fight as normal.
Krak Grenades: When assaulting a vehicle, each model using Krak grenades can only ever make one attack, regardless of the number of Attacks on their profile and any bonus attacks. Against vehicles, Krak grenades have an armor penetration value of 6+D6.
Psyk-out Grenade: When a unit equipped with Psyk-out Grenades launches an assault, any Daemons or Psykers in the assaulted unit(s) are reduced to Initiative 1 for the remainder of the phase.
Terminator Armour: Models in Terminator Armour have a 2+ armour save and a 5+ invulnerable save. Terminator armoured models have the Relentless special rule, may not perform a Sweeping advance and can be teleported onto the battlefield. They may start the game in reserve and arrive using deep strike rules, even if its not part of the mission being played. Terminators count as two models for the purposes of transport capacity and cannot embark in Rhinos or Razorbacks.

Abilities
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.
Fearless: Fearless troops automatically pass all Morale and Pinning tests they are required to take, and will never fall back. They can however go to ground voluntarily. This special rule is gained by any independent character joining a fearless unit. However, as long as a fearless character stays with a unit that is not fearless, he loses this special rule. If a unit that is falling back suddenly gains this rule, it will automatically regroup at the beginning of its next Movement phase, regardless of all normal restrictions on regrouping. Note: units with the Fearless ability are subject to the No Retreat! rule.
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 Power
Hammerhand: This power is used during the Assault phase in either player's turn, after assault moves have been made, but before any blows have been struck. If the Psychic test is passed, all models in the unit (including independent characters) have +1 Strength until the end of the Assault phase. Note that this Strength bonus is applied before any other modifiers, such as for Nemesis Daemon hammers and so forth.
