Among the most important symbols and conditions of military leadership are loyalty to the homeland, tact, enthusiasm, calmness and self-control, belief in the supreme goals of the state, realism in implementation, and effectiveness in military performance. In addition to skills related to leadership itself, such as the art of persuasion and the art of issuing orders.
