Military personnel with leadership roles may be expected to require some additional specialist training to be more effective in the NATO context, given its multinational environment. That includes the command of forces not necessarily from their own country. To describe and evaluate such leadership expectations, this article examines NATO training and uncovers the expectations defined by the training. The analysis of five courses offered by the NATO School Oberammergau helps determine these expectations in the specific areas for specific ranks and the value-added of the training and its content. For example, non-commissioned officers with ranks OR-4/OR-5 are expected to lead in interoperability, OR-6/OR-7 in rules of engagement, combating trafficking in human beings and tackling organized crime, and OR-8/OR-9 in international ethics and law of armed conflict. Commissioned officers with ranks OF-4/OF-9 are expected to lead in integrity-building and anti-corruption activities. Between 2015 and 2021, there have been a total of 1 555 trainees on these five courses that, given their ranks, could mean that they would be leading over 85 000 subordinates in deployment.
