The development of communications and especially the emergence of the internet have generated significant changes in terms of access and use of information. Since the unprecedented diversification and development of the information capabilities, the cyberspace has been accumulated a very high importance in the knowledge process of every domain. Due to these developments, nowadays the information doubles every five years and, in the future, the tempo is still increasing. In this context, at the military organization level, these new developments stress the need to find different ways to put in practice the "need to know" and "information dominance" principles. The need for "information dominance" requires reach and sound knowledge for an extensive number of people within an organization and mitigate for extended unclassified information, while "the need to know" works in exactly the opposite way - ask for classified information and restrict the number of people who have access to knowledge. Contemporary crisis responses and conflict prevention activities request decision-makers having the ability to find solutions in more responsive ways and with maximum flexibility and agility. All these qualities have to emerge from a comprehensive evaluation of information. In other words, today, there is less important for a military organization to concentrate effort to restrict access to information, but is decisive to ensure information availability for a better intelligence production which may create better premises for suitable results. For the reason that in the era of knowledge, information sharing and openness are more fruitfully for a military organization than information keeping and concealment, this study explores, in comparison, how the U.S. and Romania use internet to spread their military knowledge, doctrinal principles and procedures in the field of warfare.
