Terminator armour is the heaviest and most protective personal wargear commonly fielded by the Space Marines, a hulking suit of powered plate built for the most brutal fighting imaginable. Far bulkier than standard power armour, it encases its wearer in massive layered protection capable of shrugging off blows that would obliterate lesser troops, from tank shells to the strikes of monstrous foes.
Originally developed for lethal industrial work in the most hazardous environments, this armour was adapted into a weapon of war. It is issued to veteran warriors who have proven themselves over long service, transforming them into walking fortresses. Those who wear it are typically armed with fearsome weapons such as storm bolters, power fists, and heavy melee arms, allowing a small squad to punch through defences that would stop a much larger force.
The suit's great strength comes at a cost. Its sheer mass makes the wearer slow and ponderous, ill-suited to swift manoeuvre. To offset this, warriors in this armour often deploy directly into the thick of battle by teleporting into position, striking at the enemy's heart before they can react.
Suits of terminator armour are exceedingly rare and precious relics, each maintained with elaborate ritual and reserved for the most honoured of a warrior brotherhood's elite. To wear one is a mark of great distinction.
