Halo Scarab

The Deutoros-pattern Fortress Breaker (UNSC Type classification: Type-47B Deutoros, T-47B Ultra-Heavy Assault Platform), or Scarab, is a large, heavily armored, all-terrain, quadrupedal walker. Classified as a tier-four Excavator, the Deutoros-pattern Scarab was employed by the Covenant as a siegeworks ultra-heavy artillery assault platform. Originally for mining operations and deep excavations on widely varied terrain, the Deutoros-pattern Scarab has since been repurposed for combat.
