Challenges to national defence in contemporary geopolitical situation

This paper examines the compression of the artillery kill chain in a UAS-saturated battlefield, using the Nagorno-Karabakh conflict (2020) as an empirical case. Based on OSINT analysis, the kill chain is decomposed into measurable phases and their temporal intervals estimated. Results indicate a total duration of 60–120 seconds, making time a dominant tactical constraint. The findings highlight implications for artillery tactics, simulation models, and officer education within Joint Fire Support and Multi-Domain Operations. The study provides a transparent framework linking empirical observations with operational practice.
