I searched and didn't see any reports on this, unless I searched for the wrong thing. Guys in that video definitely agree that something is up with the divers gun and ammo. They said it was the suppressor, but I think its the ammo. Or are you supposed to be carrying regular nato ammo to use once on land, I haven't tried that yet, but I don't think it gives you other rounds simply by just picking diver as your player. And still I would think the subsonic ammo would do more damage on land.
