One of the current challenges in military units is how to sustain and strengthen military sprit of human force in order to carry out the organizational missions. In this process, various factors and parameters including health, good nutrition, good relaxation, sufficient sleep, lofty ideal, self-confidence and belief affect individual spirit. Sprit is of crucial importance in human relation, which can represent over all human relation in an organization. Spirit defined as totality of feelings, emotions and belief system, is sometimes equated with job satisfaction. Psychologists hold that the spirit refers to one’s emotional and intellectual reactions in an environment. The afore-mentioned discussion raises the question whether military labels, sign and flag can play a role in creating military self-confidence and boost their spirit of action. In other words, what is the relationship between military signs, labels and flag and spirit of military personnel? To find the answer to the question, 385 subjects from among the commanders, personnel and cadets of Imam Ali military university were randomly selected. To collect the required data, a questionnaire was distributed and the data was processed using SPSS, finding sustained positive correlation among the variables and significant effects of the independent ones. In other words, quality of apparent structure, extend of the value of position assigned, use of concept and philosophy of the sign, label and flag have positive correlation with the extent of military sprit and self-confidence.
