Units entirely with Fly ignore Terrain Features, Open Terrain and other units during Move Manoeuvres and Charge Moves.
The unit must follow the Unit Spacing rule at the end of any of its moves, and Terrain Features and Open Terrain from which the model starts or ends its move still affect it.
The charged unit is not ignored during a Charge Move, and there must be room for the unit’s Front Facing to be placed in contact with the charged unit before the Initial Align Move.

Units entirely with Insignificant do not cause Panic Tests on units not containing Insignificant when making Flee Moves through them.

A unit entirely with Light Troops can perform Reform Move Manoeuvres up to twice its Mobility (instead of the normal half Mobility).
If, while doing a Reform Move Manoeuvre, its centre moves further than its Mobility, the move is considered a March Move for the purpose of rules triggered due to Marching (e.g. Dangerous Terrain Test and, if Undead, being restricted from performing a March Move, etc.).
For the purpose of shooting, this is still a Reform Move. I.e. the unit can shoot if moving further than its Mobility.
Note: this rule has no effect on other Move Manoeuvres, including March Moves.
A unit containing Light Troops is always considered to have zero Proper Ranks; ignore Attachable Models with Light Troops joined to a unit for this purpose, unless the unit consists of only Attachable Models.

Charge Range rolls made by units entirely with Scent of Blood gain Maximised if the target of the Charge contains a Health Pool that has fewer Health Points than its starting value.

Units containing Skirmisher adopt a unique formation, called a Skirmish Formation. Instead of being in contact with each other, these models are placed 12.5mm apart from each other (roughly half an inch, see the figure below).
These gaps between the models are considered part of the unit for Cover and Line of Sight purposes, and have the same Height as the unit.
Other than this gap between models, units with Skirmisher follow the normal rules for forming units and therefore have a Front, two Flanks, and a Rear Facing, can perform Supporting Attacks, and so on.
Units in Skirmish Formation can only be joined by Attachable Models that have the same Height as the unit.
Unless an Attachable Model has the exact same base size as all Rank-and-File models in the unit, it is considered Mismatched for the purpose of placement within the unit.
The unit ceases to be in Skirmish Formation when all models with Skirmisher have been removed. When this happens, contract their Skirmish Formation into a normal formation when returning the unit into a valid formation, without moving the centre of the first rank. If Engaged in Combat, nudge any unit as normal to maintain contact.
See figure figure/skirmisher for an illustration of this rule. Skirmish formation.An example of a unit in Skirmish Formation with a joined Mismatching Character. All models are 12.5 mm away from each other.
The same unit Engaged in Combat. Only darkened models may attack. Models with a dashed frame can attack a Character (either C1 or C2). Models with a lighter shade cannot attack at all.

Units containing Solitary can never join other units, and can never be joined by other models.
Note: if a model has both Solitary and Attached, it cannot be Deployed and is therefore considered a casualty.

Command Tests taken by a unit containing this rule gain Maximised.

Rolls for Charge Range, Flee Distance and Pursue Distance by units entirely with Swiftstride gain Maximised.

Shooting Attacks allocated against a Health Pool with Hard Target suffer −X to hit.

A Charging model part with Devastating Charge, or using a weapon with Devastating Charge, gains the Rules and Characteristic modifiers stated in brackets.
For example, a model part with Devastating Charge (+1 Str) gains +1 Str when Charging.

When a model with Sweeping Attack is within 1" of an Unengaged enemy unit during a Move Manoeuvre (even temporarily), the model’s unit may perform a Sweeping Attack against that enemy unit. This can only be used once per friendly Player Turn.
Resolve the Sweeping Attack when the Move Manoeuvre is completed. The attack hits automatically, and counts as a Ranged Attack.
Each model part in the unit with Sweeping Attack must use it towards the same enemy unit. The attack causes X hits, resolved with the model part’s Strength, Armour Penetration and Attack Attributes, but not Weapons.
If values for Strength, Armour Penetration and additional Attack Attributes are defined in the bracket (Y), these are used instead. In this case, the Sweeping Attack is Unmodifiable.

During Combat Choices a model part can only choose Innate Weapons if it has no other options.
All model parts with Beast, Construct, or Mount come equipped with Innate Weapons as their default equipment and cannot lose them.
