The five armies are goblins, eagles, dwarves, elves, and men. Beorne doesn't count as an army, although it might take one to kill him. Sand worms don't count either because they are from Dune.
Note that Beorne is rescuing Thorin.
This is a miniature scene of Boromir's last stand at Amon Hen when he was defending Merry and Pippin from the Uruk Hai and orcs.
I was hoping that this was a kit or something, because I'd love to paint this. But, it appears to be a custom project someone did using games workshop miniatures.
