Due to the powerful exo-skeleton and power sources built into their armour, Space Marines in Terminator armour are capable of moving and firing with heavy weapons. On the other hand, this armour is somewhat heavy and cumbersome so Space Marine Terminators are not able to pursue a more lightly armoured foe when they flee. To represent this, Terminators that win a close combat may only consolidate; they will not be able to advance.
A model wearing Terminator armour has a 2+ armour save and adds +1 to its Attacks characteristic. Also, any model wearing Terminator armour can be teleported onto the battlefield, and set up using the Deep Strike rules, but only if the mission allows for Deep Strike to be used. If the mission does not allow troops to use the Deep Strike rules then the model must set up normally with the rest of the army.
