Resumen: This article explores the role of motivation and autonomy in the learning outcomes of students from the Spanish Army in English Language courses at the university. The courses aim to improve both their communication skills and their knowledge of specialized language (English for Specific Purposes, ESP). Second-(n = 24) and third-year (n = 47) students participated in discussions using questionnaires and semi-structured interviews to conduct a needs analysis. The results reveal that students are more motivated when practicing skills relevant to their professional and communicative goals. The study emphasizes the need for resources to foster autonomy and improve learning outcomes in the military educational context.
