Phoenix Logs/Banished Units/Scarab
From Halopedia, the Halo wiki
Superheavy assault walker with devastating excavation beam.
Few weapon platforms strike as much fear into an opponent as Scarabs. Massive and armored with nearly impenetrable battleplate, most battles end soon after a Scarab appears. Banished Scarabs are armed with an unstable plasma beam that deals incredible ground-target damage and Thrasher missiles for air defense. The Scarab is slow but very mobile and can easily travel up cliffs and across rough terrain.
Scarabs are highly prized excavation vehicles, though in Banished service they are almost exclusively used as war machines. Heavily modified by the Banished to maximize firepower, the unstable plasma generators used in these Scarabs quickly kill the Lekgolo worms that form its control system. Atriox cares not for this sacrifice as long as the Scarabs continue to bring him victories.
