During this sub-phase, powerful abilities, both magical and mundane, are unleashed in the form of special rules.

The active player chooses one of their models (usually a character) that is not fleeing and that has one or more special rules that can be used during the Command sub-phase. The player states which special rule (if any) they intend to use and, if necessary, which unit(s) will be affected, before making any tests required. The active player then repeats the process for all models in their army that have any special rules that can be used during the Command sub-phase.

Note that, unless stated otherwise, a model can only use a special rule once per Command sub-phase.
