Cooperation in multinational military operations is one of the main tasks for the Swedish Armed Forces (SAF), which means that Swedish officers need to be able to meet international military staff standards. For this reason, the SAF and the Swedish Defence University organize an annual international staff exercise which aims to train officers in and increase their knowledge of North Atlantic Treaty Organization staff methods and procedures. The essence of successful staff work is good leadership and effective team work. In this article, we present findings from three staff exercises that have significant impact on leadership and possibilities for good team learning that relate to a team learning model. These findings have great potential to be of value in planning and improving leadership education and training in both military and civilian contexts.
