I don't know if anyone already noticed this, but I was watching the Red Band trailer and saw that when Big Boss is helping Kaz walking, when they arrived at the base on the chopter, Big Boss already have the Diamond Dogs logo on his left shoulder. I always thought that Kaz was the one with the idea of Diamond Dogs. So something happens after Ocelot saves Big Boss from the hospital and before saving Kaz. Any ideas?
