Challenges to national defence in contemporary geopolitical situation

Contemporary military operations increasingly face incidents in which the nature of the hazard is initially unclear, involving possible chemical, biological, radiological, nuclear, explosive, or combined threats. In the Czech military environment, the role allocation between the Military Police and other military actors in uncertain chemical, biological, radiological, nuclear, and explosives (CBRN-E) incidents is not fully standardized. As a result, the Military Police may be expected to involve in scene control, personnel protection, preservation of evidentiary value, and escalation decisions despite limited organic CBRN capabilities. This article proposes an experimental research design for evaluating Military Police response to uncertain CBRN-E incidents under controlled but operationally realistic conditions. The model integrates tactical, technical, legal, and forensic variables and introduces a structured evaluation framework focused on decision latency, exposure risk, evidentiary integrity, coordination effectiveness, and procedural compliance. The study supports future standardization of response procedures, training, and coordination between the Military Police and specialized military units.
