The Goblins are strong in numbers their main strength is their near endless supply of goblins
Aside from them they also have some strong units like Gunbadad Guards,Cave Trolls and Stone Trolls
They also have two cavalry units the Hunting Wargs and the WargRiders
and finally they get a special hero built from their Havens the Great Goblin
I should also mention the Dragon has been removed from this version of the Mod due to time restraints and difficulties in getting the bastard to work.
