Orc-kind was a general term referring to the different breeds of Orc including Boldogs, Goblins or Gongs, Greater Orcs, Half-orcs, Hobgoblins, Snagas, Uruks, and the various sub-breeds such as the orcish trackers.
A great number of physically distinct Orc-breeds existed, as Orcs were often selectively bred for special purposes. The most notable sub-breeds were: smaller and more agile and sneaky Scouts, trackers, and Woodsmen; strong and enduring workers; heavily built and burly common foot-soldiers; and more human-like Uruk-hai Elite Warriors.
