Battering Rams and Catapults would be able to break blocks and destroy towers(even turn the tower blocks into entities so the tower falls if it is possible).

They would be good in Helm's Deep(Did the orcs use some in the film or books in Helm's Deep? I think there was a battering in the books called the Wolf's Head I think.)

You should be able to fill catapults with all sorts of stuff like lava(using a metal or stone holder so the catapult does not burn) and water, primed TNT and item entities and mobs and players.

Maybe cannons aswell that shoot blocks, lava and water, primed TNT and item entities and mobs and players.
