Great Orcs
From Tolkien Gateway
Great Orcs was a common name for the large soldier-orcs of Mordor and later also Isengard that troubled Gondor and Rohan in the late Third Age.
In fact, this name is only ever used by Éomer,[1] and may only have been current in Rohan, but the fearsome creatures it described had been known for five hundred years when he spoke these words: creatures whose name in their own Black Speech was Uruk-hai.
