The Uruk-hai and orc standard bearer are Eureka Miniatures. The Trolls are Khurusan Miniatures. The Catapult and crew are Battle Valor. The Nazgul General is Alternative Armies and all the rest of the orcs are Splintered Light Miniatures. The Trolls are used as elephants and if desired the catapult may be swapped out with the trolls.
