Fighting Uruk-Hai

The Uruk-Hai or Black Uruks, sometimes called Mazauk-Hai in Mordor to differentiate them from other Uruk breeds, were the most feared and formidable breed of the greater Orcs. The Breed was first introduced by Sauron in 2475 TA when Black Uruks of Mordor assaulted Ithilien. Later however during the war of the ring an improved breed of Uruk was introduced by Saruman. Predecessors and Prototypes of the Uruk-Hai Breed however were employed on and off long before, Great Goblins and Huge Orcs as Azog and Bolg were often thought to have been descendants of these early Kû-Uruks.

The Uruk-Hai may have been bred out of captured and magically altered Dúnedain and Black Númenoreans. Alternatively, they could be the much worn-down descendants of Boldogs, having been bred with ordinary Orcs so many times that they were shadows of their ancestors. They could also be a combination of the two, being descended from both the Númenoreans and Boldogs. In fact, considering how different the Uruk-hai of Isengard seem to be from the Uruk-hai of Mordor (one example being that the Uruk-hai of Isengard cannot see as well during daylight), it's possible that different Uruk-hai have different amounts of diverse ancestry, For example, the Isengard Uruk-hai are perhaps more human in ancestry, or at least less magically altered human ancestry (in contrast from Uruk-hai who are presumably descended from either magically altered humans, Boldogs, or both), which may suggest that Isengard Uruk-hai aren't in fact pure Uruk-hai, if there were even such a thing, and would count more as Dur-Edan half-Orcs.
