This is the actual section that holds the arms in place. It was designed to come off of the body in order for the pilot to GTFO incase of potential firery death. It attaches to the body by those two black blocks with holes in them. There are two "male" parts on the body that fit into those holes. hehe...hole. There is also a tiny piece of armour that fits on the back...dont ask me why I didnt include it here, its 5:00am right now. I made sure to include it in a later section though, so dont worry.
