Unless specified otherwise, the model that carries the battle standard cannot be the General.
Unlike normal standards, the battle standard is lost if the bearer is slain.
If a Battle Standard Bearer is in a unit, Refuses a Challenge and is subsequently moved to the rear of its unit, it loses Hold Your Ground until the end of the turn. Note, however, that if the Battle Standard Bearer has a magic standard its effects continue to apply as normal.
Combat Resolution Bonus
A battle standard adds +1 combat resolution in a close combat if it is in a friendly unit.
Hold your Ground!
Friendly models within 12" of the Battle Standard Bearer re-roll failed Panic and Break tests. This ability cannot be used if the Battle Standard Bearer is also fleeing.
If your Battle Standard Bearer has a Line of Sight value of 5 or more, then the range of their Hold Your Ground ability is increased by 6".
