The Fighting UrukHai are back!!! (download at: http://viwright.com/1lJJ)

And just to be perfectly clear, below is a short entry about UrukHai.

In Peter Jackson's film trilogy, Saruman's Urukhai are bred from pits beneath Isengard and when the time is "right" they are dug up by lesser orcs working for Saruman, who are occasionally killed by the newborn Uruks. Jackson's depiction of the Uruks being spawned from the mud came from Tolkien's old description of orcs being "bred from the heats and slimes of the earth." It is said they were a result of crossbreeding orcs and "Goblinmen", instead of Orcs and Men. In Tolkien's writings "Goblin" is just another term for orc.

The film versions of the Urukhai tend to be tall, broad, burly and with long black hair. The first of them is Lurtz, an original character, who is the first of Saruman's Urukhai to be bred. The Uruks are also shown to use crossbows at Helm's Deep, though Tolkien does not mention the weapon in the book. Berserker Uruks were also used during the siege of Helm's Deep, both to clear the ramparts of defenders and to detonate explosive mines to breach the deeping wall. These Uruks were very tall, wore no armour and were prepared for battle (and most likely death) by donning helmets filled with the blood of their enemy.

Sauron is shown to have bred his own Urukhai, known as Black Uruks. They can be seen when Frodo is captured by the orcs of Cirith Ungol and his mithril shirt leads to a confrontation between Shagrat, a Black Uruk of Mordor, and an orc from Minas Morgul called Gorbag. Gorbag threatens to stab Shagrat if he tries to steal the shirt, but he tosses it aside and throws Gorbag down a long flight of stairs, where he falls on top of several other Urukhai. A huge brawl between orcs and Urukhai spreads all over the fortress, allowing Sam to enter the tower with ease.
