Introduction and objective: In September 2024, Lower Silesia was affected by an unprecedented flood, resulting in the destruction of infrastructure, limited access to healthcare, and an increase in epidemiological risks. In response to this situation, the Military Health Service, as part of the Military Task Group “Lower Silesia,” took action to support the national healthcare system. The aim of this study was to analyse the activities of military medical teams carried out during the rescue operation in the aftermath of the flood, identify operational challenges encountered, and develop recommendations for future interventions in crisis situations. Materials and methods: The study was based on the analysis of operational reports, medical documentation, and field observations of the activities undertaken by military medical teams. The organizational structure, areas of operation, and scope of healthcare services provided were described. Results: Over the course of seven days of operations, the military medical teams provided assistance to 338 patients, mainly those with respiratory infections, injuries, and exacerbations of chronic diseases. A total of 126 post-exposure vaccinations were also administered. Organizational challenges included difficulties in the continuous supply of medical materials, limited communication, and the absence of clear logistical procedures. Conclusions: The actions of the Military Health Service played a crucial role in stabilizing the health situation in the flood-affected areas. Based on the experiences gained, the need for better organization of logistics, communication, and resource acquisition in similar operations was highlighted.
