The Siege Ram is the final unit of the set of battering rams. Upgraded from the Capped Ram (which as a clever joke is capped with a ram's head--get it?), it has more HP and larger armor and bonuses. It still, like its predecessors, retains the feature of granting melee units attacking it a +3 attack bonus. Sadly, it's not available to a few civs. Rams can also carry foot soldiers, which increase its speed and attack bonus vs. buildings; the Siege Ram can carry six.
