Are the parts shared or can you have all 3 built at same time?

The Battalion includes 3 complete kits for building a ballista, bombard and catapult with no sharing of parts. For further details contact us as help@natgeotoys.com

Wood glue is not required, but can be used if desired. Keep in mind if using glue some pieces need to move freely, therefore must not be glued.

Does the battalion kit (with all 3) come with 3 separate instruction booklets so I can split it up for party favors?

Our order did not come with separate instructions. As well the instructions were not clear and vague. Lacking in actual instructions and the pictures were not clear or in color. That normally would not matter but some of the parts were so small and looked so much alike that we had a hard time determining what part went where. To be honest I thought this was a great idea. However, it took so long to assemble and did not perform when done that it was a let down. I will not get this again even as a party favor.

Are the rubber bands latex? If so, what size are the bands?

Yes, these are a latex band. They are approximately 1 1/2" or 3.81 centimeters.
