Alot of people who have just seen the movies assume that Saruman created the Uruk-hai when in fact Sauron did about 500 years before the end of the third age. Saurons uruk-hai were shorter and had longer arms then Sarumans who were basically mansized and stature.
Will there be weaker Uruk-hai then Isengards in the units of Mordor as elite heavy infantry soldiers for them, i belive this would follow the books.
