The central theme of this issue is asymmetric threats with emphasis on the new role of the armed forces as one of several possible national responses. Asymmetric threats are not a new phenomenon. According to the literature, they are one of the oldest forms of threats, although in most cases the term asymmetric is not specifically mentioned. Asymmetry as a term referring to something that is not symmetrical or equivalent emerged later than the threats we today identify as asymmetric, and is consequently considered more modern. In reality, asymmetry is a form of threat that no one expects. It can relate to the organizational, personnel-related, and quantity-related aspects or some other aspect. It is important to note that an asymmetric threat emerges in a way that comes as a surprise. Our responses are therefore delayed, since such a threat was unexpected and we are not (yet) properly prepared to counter it. For this reason asymmetric threats are a big challenge. We can deal with them in different ways; one of them is certainly military. In asymmetric warfare, a very important effect is demonstrated with the use of minimal input, assertion of various interests – most often of an individual or group against a larger group or country – innovative approaches, and with high efficiency compared to the resistance of the target. When considering the role of the armed forces and their response to asymmetric threats, both the question and the answer to whether this should be the new role of the military are quite obvious. Asymmetric threats are a series of threats with a rich history, but it is their very innovation, effect of surprise, and inflicted damage that require a great deal of vigilance on the part of all whose fundamental mission is to ensure national security. In the past few years, Slovenia has faced various threats that could be classified as asymmetric, such as floods; ice storm; mass, group and individual illegal migration, and COVID-19. The state responded to them by activating various stakeholders, including the military. With its numerous past experiences acquired at home and abroad, the Slovenian Armed Forces has successfully joined state activities to normalize, assist in, restore and resolve the existing situation, and to provide order and security. Nevertheless, all stakeholders in the country who are involved in the efforts tackling the emerging asymmetric threats, including the Slovenian Armed Forces, are constantly faced with new challenges. These are manifested in various forms such as the need for new knowledge, other forms of cooperation, provision of specific logistical support, changes in legislation, modernization of the self-protective equipment for the employees and the efficiency of communication and other devices. In order to be better prepared and more responsive to asymmetric threats in the future, we still need to do more to face the above-mentioned challenges. There are several ways to do this. One of them is to write articles on the role of the armed forces in asymmetric threats. The authors of articles in this issue share a variety of experiences, views and ideas on how to proceed in order to be better prepared and more effective in the future.
