Myrmidon Destructors

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.
