The authors, in their contribution, which has the character of review studies, compile the knowledge, findings, and conclusions they have reached in previous studies and researches. Their aim is to evaluate the possibilities and limits of ethics education in the conditions of the University of Defence and to design a model of ethics education for military students - future military leaders. Authors concluded that it is necessary to extend the existing teaching of theoretical and applied ethics and to connect it with a suitable tool enabling the long-term development of students - future military leaders. The authors' proposed model of ethics education, therefore, represents a construction involving the theoretical background, identifying subjects and objects of ethics education and their interactions using the proposed application of the method, "11 Principles of Effective Character Education" by Thomas Lickona and Matthew Davidson into the conditions of the University of Defence. The acquired knowledge will be used by the authors in the draft of the Model of Ethical Education and Ethical Leadership of the Czech Armed Forces.
