The article focuses on the social aspects of corporate social responsibility (CSR) in the Czech Armed Forces (CAF) and, more specifically, on professional ethics as a prerequisite for the sustainable development of the security organization. The text presents the results of research conducted on a sample of 278 members of the CAF. This research was based on Schwartz’s holistic concept. To determine value orientation, a reduced version with 21 entries of the Schwartz’s Portrait Values Questionnaire (PVQ) was used. Our data indicate that value orientation changes depending on military rank, depends, to a certain degree, on trait conformity (including obedience, respect for authorities, politeness, and self-control), and increases in the presence of lower-ranking individuals. Based on these findings the authors recommend to continue monitoring the value profiles of CAF members at various stages in their careers, to determine the optimal range of self-identification with a certain military rank and position, and to provide rank and position-specific educational programs into military ethics and ethical leadership aimed at sustainable development of moral-values.
