Extraordinary Discipline: The commanders of this elite formation, and the warriors they lead, are some of the most skilful in all of the Mortal Realms. If this battalion is part of your army, at the start of your hero phase, roll a dice for each HERO in this battalion that is on the battlefield. On a 4+, that HERO can issueacommand in that turn without a command point being spent.
To use a command ability, you must spend 1 command point, pick 1 friendly model to issue the command, and pick 1 friendly unit to receive the command. Unless noted otherwise, the models that can issue commands and the units they can issue them to are as follows:
Unit champions can issue commands to their own unit (see 22.3.2).
HEROES can issue commands to units that are wholly within 12" of them.
Generals can issue commands to units that are wholly within 18" of them.
TOTEMS can issue commands to units that are wholly within 18" of them.
Each command ability will say when it can be used and what effect it has on the unit that receives it. A model cannot issue more than 1 command in the same phase and a unit cannot receive more than 1 command in the same phase. In addition, you cannot use the same command ability more than once in the same phase (even for different units).
