Unchained Conviction

(Rule)
Description: A unit composed entirely of models with this special rule whose controlling player fails a Pinning check made for it is not Pinned, but instead must immediately move 7" directly away from the enemy unit that caused the Pinning test, moving each model in the unit directly away from that enemy unit by the shortest available path. If this would bring the unit into contact with the edge of the battlefield, do not move it any further. Once all models in the unit have been moved, there are no further effects and the unit is not Pinned. If the unit is required to make this move during a Charge, then the Charge automatically fails and the unit is Displaced from the position it occupied when the Charge was declared.
