James big difference, yes a regular cast Dutch oven could be used over coals or a camp fire. I have a foam or round top cast with the bail handle that could be used like that. What these guys are referring to are actually called cast iron camp stoves. They normally have 3 legs and a flat top with a lip around outside edge for holding charcoal or embers from a fire. They just get referred to by most people as Dutch ovens.
