At least since the beginning of the most recent Russian invasion of Ukraine and the massive use of unmanned aerial vehicles, it has become imperative to elaborate potential countermeasures, that is, counter-unmanned aerial systems. Accordingly, based on past and ongoing conflicts – including the war in Ukraine – this paper analyses the impact of technological changes on warfare. Specifically, it takes a closer look at the types of unmanned aerial vehicles deployed on the modern battlefield and how critical infrastructure, soldiers and civilian populations could be protected in the face of these novel threats.   »» TDHJ «« » patreon: https://www.patreon.com/thedefencehorizon » donate: https://tdhj.org/about/#donation »» HOME «« » https://tdhj.org/ »» SOCIAL MEDIA «« » X (formerly Twitter): https://x.com/HorizonDefence » Facebook: https://www.facebook.com/thedefencehorizon.org » Instagram: https://www.instagram.com/thedefencehorizonjournal/ » LinkedIn: The Defence Horizon Journal
