The Hunter orcs were a ruthless group of Orcs who followed Fimbul and Yazneg, who served Azog. The Hunter Orcs that roam the lands east of The Misty Mountains are a particularly aggressive kind of Orc. Wild hunters who don't really mind much what prey they're after—Hobbits, animals, men—they're not picky eaters. Mounted on hoards of vicious Gundabad Wargs, they can quickly cover and control large territories. The hunter orcs do not speak common tongue but they speak an ancient orc language. Indicating they are proud of being orc and despise man.
The games workshop description. The fast-moving and fanatical Hunter Orcs serve as the right hand of Azog, a relentless band who will stop at nought to slay his quarry.
