It has to stated that the assumptions of Joint Vision 2020 concept are directing American armed forces’ transformation denoted as the “future joint force”. It is assumed that the goal of the mentioned above transformation is to create forces dominating in the whole range of military operations. They are to be faster, more effective and at the same time feature more precision than today. Moreover, it is proposed to continue investing in new technologies and developing required capabilities. An explicit consequence is that technological development supports the pursuance of intended goals relating to conducted transformations. American experts claim that opinions expressed so far have to be revised and based on information as the key factor affecting military operations as it determines the shape of future military forces. According to these experts, information is to replace the enemy’s physical attack. Therefore, an answer must be found to the question how to affect the enemy using information, disorganise his information systems and protect own systems against failures. A great stress is also placed on finding an appropriate way to increase capabilities relating to information acquisition, transformation and distribution on time and then to use the information in an appropriate way. The superiority, or even dominance, of information becomes one of the most important areas affecting directly the idea and significance of modern theory of military operations. The thesis mentioned above is reflected in the Joint Vision 2020 concept.
