Brumak

&nbsp The Brumak was a massive Hollow creature, capable of pushing over an Assault Derrick  with a single shoulder shove.COG research indicates that they were bred from apes by the empire, often growing to about 15 meters in height (49 feet) and weighing around 15,000 kilograms (33,069 lbs).|[1] These huge monsters have extraordinary thick hides, even without their heavy armor. They are deadly at close range. For long range attacks, they carry wrist-mounted chainguns and a back-mounted rocket launcher. There are rumors of Brumaks carrying energy beam cannons instead of the chainguns. Brumaks only have two eyes, but their helmets are covered in glowing lamps giving the illusion that they have more.No Human has ever attempted to ride one. After E-Day, at least three Brumaks were seen fighting COG forces
