Goblin-men
From Tolkien Gateway
Goblin-men were a people or race of creatures that were bred by Saruman, apparently by blending the races of Orcs and Men.[source?]
They were similar with the Half-orcs, at least in their resistance to the sunlight, an attribute that differentiated them from the full Orcs.[1]
The Squint-eyed Southerner was possibly a Goblin-man, as Frodo Baggins commented that he looked "more than half like a Goblin."[2]
Goblin-men fought alongside Half-orcs, Hill-men and Dunlendings in the Battle of the Hornburg.[1]
