In a more sophisticated design, a battering ram was slung from a wheeled support frame by ropes or chains so that it could be much more massive and also more easily swung against its target. Sometimes the ram's attacking point would be reinforced with a metal head and vulnerable parts of the ram might be bound with metal bands. Many battering rams had protective roofs and side-screens covered in materials, usually fresh wet hides, presumably from the animals eaten by the besiegers, to prevent the ram being set on fire, as well as to protect the operators of the ram from enemies firing arrows down on them by allowing them to seek shelter within the battering ram structure. The image of the Assyrian battering ram shows how sophisticated attacks and defences had become by the 9th century BC. The defenders are trying to set the ram alight with torches and have also put a chain under the ram. The attackers are trying to pull on the chain to free the ram, while the aforementioned wet hides would protect against the fire.

In castles, defenders attempted to foil battering rams by dropping obstacles in front of the ram, such as a large sack of sawdust, just before it hit a wall, by using grappling hooks to immobilize the log, by setting the ram on fire, or by sallying to attack the ram directly. The Romans used it as a battle tactic.

Battering Ram
Some battering rams were not slung from ropes or chains, but were instead supported by rollers. This allowed the ram to achieve a greater speed before striking its target and was therefore more destructive. Such a ram, as used by Alexander the Great
