They were some iteration of Bokoblins (or whatever). Moblins are the larger, fat-headed pig-dudes.
These guys in the sunset are much like WW's Bokoblins. They're small, their heads hang low, they're green, they mask their mouths/nose, they have little beady red eyes, they have horns sprouting from their temples, and in the trailer the frontliners of the pack had quivers with arrows in addition the clubs they wielded.
