Dealing with the protection of national and EU’s critical infrastructure will always be an important task for experts and professionals seeking to foresee possible future threats and risks to them, also searching for solutions. While examining given circumstances and existing processes and protocols there is no doubt that the job has been well done, on the other hand, it is not over yet. And if it is true in connection with national and EU’s infrastructure, it is supposed to be true pertaining to infrastructure of deployed forces. I am quite sure that many of the readers of this topic have some memories of faraway locations somewhere in the Middle East where our troops have been deployed to help restoring peace and stability. Taking this parallel and considering the current situation in eastern Europe, putting more focus and effort on protecting critical infrastructure of possible deployed forces seems inevitable. In other terms, what experts and professionals have foreseen a decade ago, is the present now, no matter if we look at asymmetric or near-pear conflicts. Both situations show an extreme increase in the use of unmanned aircraft systems aiming to harm and destroy vital services to break down the willingness and capabilities of an adversary. Taking all of this into consideration, I see a realistic need to examine the threat posed by unmanned aircraft systems carrying improvised explosive devices. For this, my aim is to draw attention to this relatively neglected area and focus on finding usable solutions for the future.
