How to make an origami tank Type 10 ( Version 1) 2, gun turret

Hello, I am Hiroshi. I am Japanese Army 1st lieutenant in reserve. This is a tutorial how to make a gun turret of The type 10; Japanese newest main battle tank. This is the most basic origami tank of mine. I do not think I have to make a tank with one sheet of paper because the gun turret should turn around and fire to all direction.
