[@Simple Unicycle], Oh! One more thing, in earlier arcs, the Brotherhood found a Construction Droid, which is described as this:

[quote]And what was inside that chamber was almost as valuable; a giant treaded vehicle that would seem like a strange form of tank at first, if not for the giant crane arm that jutted out from the top of the roof. A Construction Droid. No, wait, not just a Construction Droid, but a Construction Droid equipped with a giant laser and mortar - nearby manuals would reveal that its purpose was for demolishing buildings. Not merely that, but there was, attached to its very back, a 'recycling device' that recycled metal and stone into new building materials...[/quote]
