Models with the Very Bulky special rule can only Embark on a model with either the Large Transport (X) or Large Assault Transport (X) special rules. In addition, models with the Very Bulky special rule count as two models for the purposes of determining how many models a Transport can carry.
Hits scored by a weapon with the Light trait against a model with the Armoured special rule count their AP as 0. In addition, a model with the Armoured special rule may re-roll failed Save rolls made against Hits scored by a weapon with the Light trait.
Detachments with the Commander special rule are the commanders of your Army. When deploying a Formation that includes any models with this special rule during deployment, a player must assign all models with this special rule to a Detachment in that Formation, so long as the two are of the same Detachment type. For the remainder of the battle, the model counts as part of the Detachment it is attached to an cannot leave it for any reason. A Detachment can only ever have one model with the Commander special rule attached to it at any given time. If, for whatever reason, a model with the Commander special rule cannot be assigned to friendly Detachment during deployment (e.g., due to there being no Detachment of the same type in the same Formation) then it acts as its own Detachment on the battlefield.
Friendly Detachments within a number of inches equal to the value shown in brackets of a Detachment with this special rule may use this Detachment's Morale value in place of their own when making Morale checks.
A model with the Invulnerable Save (X) special rule gains an additional Save characteristic equal to the number shown in brackets, referred to as an Invulnerable Save. Invulnerable Saves are not modified by a weapon's AP characteristic.
A Detachment that contains one or more models with this special rule may issue a command when it is activated. If the controlling player chooses to do so, they may select one other friendly Detachment that has yet to be activated this round, and is within 6" of one or more models with this special rule that are being activated. The selected Detachment's Order token is discarded and replaced with a different Order they were eligible to be issued during the Orders phase of this round. A Detachment issued with a Fall Back Order cannot discard its Order via this rule, however a Broken Detachment can, and thus can be issued an Order other than Advance or Charge.
A Detachment which contains one or more models with the Implacable special rule does not take Morale checks when they lose a Combat. Instead, the controlling player may choose if the Detachment Withdraws or not. An Engaged Implacable Detachment that does not Withdraw remains Engaged; if no models in the Detachment are in base to base contact with an enemy model, the Detachment does not move and is no longer Engaged.
