The narratives of military nurses during the Civil War in Marawi City are often overlooked. While the public hears tales of brave soldiers, they tend to forget the crucial role of medicine and first aid. This study highlights the experiences of deployed military nurses and the challenges they faced during the Marawi siege. Using a descriptive phenomenological approach, the researcher sought to understand participants' behaviors from their perspectives. The study received approval from the Research Ethics Committee and the Office of the Chief Nurse of the Armed Forces of the Philippines (AFP). Confidentiality and anonymity measures were adhered to. Four participants were selected through criterion sampling, and data were collected via semi-structured interviews. Narratives were transcribed verbatim and analyzed thematically using Braun and Clarke's steps. Four (4) dominant themes emerged: (1) The Interplay of Key Roles in Times of Conflict, (2) Triad of Tactical Nursing, (3) Overcoming the Barriers, and (4) Echoes of Valor. The study reveals that military nurses play a vital role in providing essential medical support to injured personnel but face challenges like emotional stress, logistical issues, and limited resources. Despite these obstacles, they remain dedicated to their duty and proud to serve their country. The study faced challenges including a lack of literature on deployed military nurses' intervention challenges, complicating the literature review. Finding suitable key informants was also difficult, as was ensuring stable internet connectivity during online data collection. Additionally, the recency of participant memories posed a potential obstacle to gathering accurate and detailed information.
