The Uruk-Hai Battering Ram was one of the most fearsome weapons used at the Battle at Helm's Deep. Orcs used it to bash down castle gates and doors. It was also a very deadly weapon as its reinforced metal cap could maim and eviscerate warriors.
The battering ram was a large, heavy log with a cap at one end that had bayonets. It was dragged by a few Uruk-Hai soldiers and they used it to destroy castle gates and doors. It proved to be fearsome because of its effectiveness in combat; the Uruk-Hai continually used it, as it pierced through castle gates and bashed them down one by one, until finally reaching the keep, where it would have been successful in the genocide of the population.
