A model part with this rule can exchange all of its normal Close Combat Attacks for a single Special Attack, which cannot be made as a Supporting Attack, is resolved at Initiative 0, has Strength 10 and Multiple Wounds (Ordnance). Crush Attacks never benefit from any equipment or special rule the model may have (since it is a Special Attack). Even though this is a Special Attack, the attack is Allocated as if it was a normal Close Combat Attack. The model can still make other Special Attacks such as Stomp or Impact Hits.
