The article shows the expression of social innovation in the Lithuanian military. By presenting different innovation models and processes, the authors argue that social innovation could be an effective tool for increasing the efficiency, resilience and intelligence of the armed forces. While the general public perception of the military is very technocratic, social practices (leadership, collaboration, communication) can broaden that perception through social innovation. The empirical study reveals that the expression of social innovation enriches social practices, and introduces new perspectives, ranging from advanced mental health support measures to operational collaborative strategies. Social innovation can contribute to the management of contemporary challenges both in the military and in society. By presenting the current expression of social innovation, the paper reveals the opportunities for improving social innovation in the Lithuanian military.
