anti-siege golems

Siege golems are smarter golems built specifically for large scale war, rather than defence against pillagers and zombies. They would spawn in castles, martial villages or rarely in large villages. They are made to desperately use anything and everything available to them to ward off massive sieges.

Siege golems would look like a skinny iron golem, but with a shield on one arm and a small bit of Redstone at the end of the other. It would not give villages flowers, but it will use its shield to defend them from projectiles. They are faster than iron golems. When attacking, they would do less knockback and damage than iron golems. They could also activate Redstone contraptions and pick up and throw placed explosives.

They could pick up and use items like foxes, but only combat-related ones.

If you attack a villager or raid a chest while they are watching, then they will attack you.

They might be used as soldiers in castles, and would be capable of operating siege weapons. If their enemies are underneath them, they would pick up and throw large animals at enemies, or drop boiling oil on them.

They can use bows.

They would be summonable using the following structure:

An anvil on top of a chain block, with iron bars on either side, and a jack-o-lantern (not a carved pumpkin) on top.
