Chaos Space Marines in Terminator armour are capable of moving and firing with heavy weapons, thanks to the powerful exo-skeleton and power sources built into the armour. In addition, they may move and shoot twice up to 12" or once up to 24" with rapid fire weapons. On the other hand Chaos Terminators are somewhat cumbersome, so they are not able to pursue a more lightly armoured foe when they flee. To represent this, Terminators who win a close combat can only consolidate, not advance.
Any model that is equipped with Chaos Terminator armour has a 2+ armour save and also adds +1 to its Attacks characteristic.
In addition to this, any models who are wearing Chaos Terminator armour can be teleported onto the battlefield and set up using the Deep Strike rules – but only if the mission allows for these rules to be used. If the mission does not allow troops to use the Deep Strike rules, then the models must set up as normal with the rest of the army.
