Abstract
In the fight management, the military commander, who is assimilated to a leader has, most of the time, the most important role. Today, in addition to the traditional missions to defend the sovereignty, independence and territorial integrity of the state, the military forces also carry out missions according to the obligations assumed by NATO or EU membership: peacekeeping, peace enforcement, humanitarianism, post conflict reconstruction, terrorism, security and collective defense. These missions require the adoption of modern forms and methods of leadership, especially as they are largely executed outside the national territory, which provokes new cultural expectations and demands, involves ethical issues and legal advice whose value is not fully known.
