The growing participation of the Armed Forces (AF) in natural disasters situations has ratified the importance of deepening and improvement of studies in humanitarian logistics in the military field. Knowing that excellence in processes can generate savings of resources to be mobilized to meet the needs of the affected population as well as minimizing the response time, this study aims to present and analyze the response activities to natural disasters performed by the Brazilian Air Force (BRAF), from the perspective of process modeling. For this, a case study is carried out according to the mapping of activities performed by the BRAF based on the legislation in place and on a real operation of support to victims of a disaster in the mountainous region of Rio de Janeiro in 2011, considered one of the biggest climate tragedy in Brazil. Simultaneously, a pattern matching comparability in relation to the academic literature is conducted. The results of this study point to processes performed by the BRAF that can be considered in the preparation of a specific doctrine on the subject and to processes not considered in current legislation, which may be the subject of future research in the BRAF. It also suggests the inclusion of processes not represented in process models of disaster response in the academic literature. Thus, it aims to support future studies in academic research on the subject, as well as contribute to the development of a specific doctrine on these activities in order to achieve greater effectiveness and efficiency in the BRAF support for humanitarian missions.
