This thesis examines how military professionalization is realized in the everyday practice of Swedish Air Force officers. Situated within war studies, the study explores how professional expertise is developed and sustained through the interaction of formal education, organizational conditions, and service demands. Empirically, the thesis draws on a qualitative case study at Blekinge Air Wing, using semi-structured interviews. The material is analyzed through an ideal-type approach, identifying three professionalization logics: practice-driven professionalization, education-driven professionalization, and professionalization through expected expertise. These logics are subsequently related to Karl Ydén’s tentative model for analyzing military professionalism, applied as a diagnostic tool to identify patterns of fit and misfit between education, occupational practice, and organizational expectations of expertise. The findings contribute a practice-oriented analytical approach for studying Military Education (PME) in organizationally complex military settings.
