Ultramarines - Marneus Calgar in Armour of Antilochus (55-74)

The greatest Ultramarine besides the Primarch himself, Marneus Calgar is equally potent a warrior on the battlefield as he is a leader in the command bunker. While he often deploys in an artificer-crafted suit of Gravis armour, he has also been known to still wear the ancient Armour of Antilochus. This relic Terminator armour suit incorporates the Gauntlets of Ultramar – and Calgar operates it with enough agility that he can join almost any infantry squad the Ultramarines choose to field in battle.
