In
J. R. R. Tolkien's
fictional realm of
Middle-earth,
Uruk Hai are a cross breed between
Orcs and
Men. The Orcs make up
Saruman's army of 10,000. They are faster than normal Orcs and can travel during the day without being weakened. These Orcs aren't only faster but smarter, stronger, and bigger. The army of Uruk-hai fought against King
Theoden and his people at
Helm's Deep.
