The Brumaks are enormous walking tanks for the Locust Horde. They have weapons on their wrists and back. On the wrists there are turrets and on the back there is an enormous rocket launcher that shoots multiple missiles. One Brumak only appears in Gears 1 but a lot of them show up in Gears 2. When facing a Brumak, it's weapons must be destroyed first before you can actually kill it or otherwise you might die. It's actually been known in DNA analysis that the Brumak comes from a type of ape in the Locust Horde. It takes a while for these things to grow into the giant monsters we know and like today. Don't believe me? Check the Gears of War wiki and tell me I'm wrong.
