Grond in the New Line film
Battering Ram of Sauron's forces during the Siege of Gondor. Grond was said to have come from deep inside Mordor. Its hideous was made of solid steal and flames danced inside of it. When the Orcs of Gothmog's companies failed in opening the gates of Minas Tirith, the Great Beasts were commanded to bring forward Grond. The orcs chanted the battering ram's name until finally the gates were open and orcs and trolls poured into Minas Tirith, killing all in their path.
