In the Movies the Orcs of Mordor are among the most diverse Orcish factions.They seem to belong to many different specialized breeds ranging from smaller workers or Snagas to smaller Scouts and broad-nosed Trackers to squat and muscular Fighting-Orcs, somewhat taller Hobgoblins and larger and better armed Morannon-Orcs to Black Uruks of Mordor, apparently belonging to the same breed as the Isengard Uruk-Hai though with a somewhat different skin-tone and equipment.
