Challenges to national defence in contemporary geopolitical situation

The capacity of military organisations to sustain operational effectiveness depends increasingly on their ability to lead and retain Generation Z personnel (born 1996 – 2012) – the first fully digital cohort entering professional armed forces worldwide. This narrative literature review synthesises evidence on the leadership challenges and opportunities associated with Generation Z, with particular focus on the Czech Armed Forces (CAF). Drawing on generational theory, transformational and adaptive leadership models, as well as empirical military research (2019 – 2025), the paper identifies three analytical dimensions: generational characteristics in military contexts, leadership and development requirements, and institutional adaptation within the CAF. Evidence-based implications are developed for leadership doctrine, training design, and organisational culture.
