Background <p>Effective disaster response requires both well-prepared medical rescue teams and resilient early-phase logistics.</p> Objectives <p>This study examined how medical rescue teams’ personnel prepared, mobilized, and maintained field living conditions after the 6 February 2023 earthquakes, aiming to generate practice- and policy-oriented recommendations.</p> Methods <p>A qualitative phenomenological design with purposive maximum-variation sampling (<i>n</i> = 12) was utilized. Semi-structured online interviews underwent thematic analysis. Reporting adhered to COREQ standards. Ethical approval was obtained and informed consent secured.</p> Results <p>Three themes emerged. (A) <i>Team Structure and Personnel Characteristics</i>: Professional diversity enhanced capacity only when roles were explicit and leadership was visible; inconsistent training and leader ambiguity created tension. (B) <i>Assignment</i>,<i> Preparedness</i>,<i> and Deployment Process</i>: Notification and assembly often relied on informal channels (e.g., messaging apps); mission orders and destinations were unclear; winter hazards and traffic impeded deployment; initial 3–7&#xa0;day rotations were perceived as most effective. (C) <i>Base-of-operations and logistics</i>: Early shelter, heating, nutrition, and hygiene support were inadequate, with privacy and sanitation being major challenges, but these improved as institutional logistics scaled up.</p> Conclusions <p>The performance in the early phase can be strengthened by standardized pre-deployment checklists and mission orders, dual leadership including an experienced member, short initial rotations, and minimum living-condition standards. Competency-based modular training, regular drills, and mandatory after-action reviews are further recommended to institutionalize learning.</p>
