But nothing is ever truly immortal. Hence why skulls of Necron immortals lay at their feet as they walked. The Astartes with the brand new armour, Damien, took point. His armour was home to special features... he was a space marine scout squad and tactical squad all in one. He wielded a stalker combi bolter/plasma single-handedly, as his helmet was programmed with many independent features, including an unparalleled targetimg system. Not only that, but he could detect anything within a mile.
