An Armoured elite melee unit equipped with a Thunder Hammer and a Storm Shield. They are deepstriked when produced. They are produced in the Chapel-Barracks.
Assault terminators are tanks. They can take a lot of damage and cause just as much. However, they have no ranged attack and are very slow so prepare to lose them if you send them in on foot. Luckily, Terminators can be equipped with teleporters which means you can teleport them right into enemy lines. A good idea is fully reinforce them first then deepstrike them via orbital relay. Alternatively, land raiders can transport them into combat and provide cover fire.
