I'm a little confused. The legendary Stone Rhino (Behemoth), is armed with 2 Large Pulse Lasers, 2 Gauss Rifles, and 1 Small Pulse Laser. Correct? However, in the pictures of this mech, there's only one large barrel above the cockpit instead of two. Can someone please explain to me why there aren't two above the cockpit to fit the description of the mech instead of one?
