Warhammer 40K - Ultramarines - Terminators (preorder Q4)
Terminators are Space Marine Veterans who have earned the right to wear Tactical Dreadnought Armour, better known as Terminator Armour. They are their Chapter's greatest infantry assets, each essentially serving as a walking tank.
Tactical Dreadnought Armour combines the technological developments of power armour with the sealed environmental suits designed for starship crews that work in highly unstable or corrosive environments such as inside the high pressure casings of Plasma Reactor shields. It can even withstand the colossal impact of high speed orbital micro debris.
Terminators are always members of the elite 1st Company of a Codex Astartes-compliant Space Marine Chapter.
