The state of uncertainty in the strategic environment has been a challenge throughout human history. The term „fog of war“ introduced by Clausewitz refers precisely to the problem of uncertainty in situational awareness, and the terms nature of war and character of war (Clausewitz) also suggest a challenge in the very definition of war. While the nature of war is constant, its character evolves, and this can affect the application of an appropriate response to the threat of war. Such is the nature of, for example, hybrid warfare or the war against terrorism, which requires a different approach from the traditional understanding of national security. Today's intelligence analysts must be not only creative, but also able to imagine a new threat before it actually materializes. Without awareness of the current situation in the strategic environment and the trends that shape it, it is almost impossible to predict and develop future scenarios. If we add to that today's picture of a very complex and dynamic world, strategic forecasting is becoming an increasingly important tool for organizations and individuals in adapting to changes, anticipating risks and taking advantage of opportunities. Rapid changes in technology, socioeconomic, political factors and many other factors, due to their complex nature, often lead to unpredictable situations that require a deeper understanding of future trends and possible scenarios. Precisely for these reasons, strategic levels increasingly need experts and professional people in different fields, who will work together to get a more complete picture of the situation and provide the information necessary for decision-making. The aim of this paper is to define strategic forecasting as a key concept and as a tool for making effective and timely decisions. Strategic forecasting is fundamentally qualitative, but also quantitative in nature and includes not only the military dimension, but also others such as political, diplomatic, economic, social and others that are often crucial in relation to the military, but this seminar paper will deal with mostly only in the military dimension.
