The paper observes that a socio-cultural phenomenon has occurred in the Defence community whereby it is has become commonplace for the assumption to be made that success in various types of modern warfare will be assured if Information Superiority can be achieved. It presents outline arguments that suggest that this assumption is fallacious. It concludes that: • Success in Network Centric Warfare requires Knowledge Superiority and benefits from Information Superiority. • Success in Manoeuvre Warfare requires Knowledge Superiority and benefits from Information Superiority.
