Goblins are large Great Orcs, Uruks. They are sometimes fat or not, short or tall, gluttonous and with a pale yellow orange or a grey green. They inhabited the Misty Mountains and were known to tame Wargs and were know to be the engineers atop the siege beasts. They were used as common as the normal Uruks but were known to be good at making weapons of war. They experimented with fire and chemicals with results as blasting powder or projectiles thrown from Siege Graugs' catapults. For their devastating minds they were kept as the best in Sauron's Army. The Dark Lord Sauron valued their technology and power so he used some as soldiers or guards, some as sappers, some for riding Siege Beasts and some as archers.
