Operator Vandals are unique Vandals from the House of Salvation. They carry a Operator Augment and are first seen in the Deep Stone Crypt Raid.
They reappear in the raid in many encounters, most notably in the Crypt Security and the boss battles against Atraks-1, Fallen Exo and Taniks, the Abomination.
