Scarab

Developed in an advanced construction site, Scarabs are mobile fortresses. The quadrupedal behemoths are typically deployed from low or medium orbit, or from high atmosphere. They are used to attack heavily-defended structures and emplacements and often lend quick but unstoppable support to Covenant troops on the ground. They are extremely powerful, possessing an exceptionally destructive plasma beam as well as one or two dorsally-mounted anti-air cannons. Their bodies are massive and multi-leveled and posses four legs. Unlike most Covenant vehicles, Scarabs do not use antigravity propulsion to move. Scarabs instead walk using their massive legs, which are surprisingly swift and precise given their massive size. The legs can also be used to crush enemy forces on the ground.
