There are two challenges in application of ethical principles: one is about adopting appropriate methods and the other one is resolving the conflicts within the principles and methods. Some of the principles are widely used in some professions. For instance, in army, especially the relationship between commanders and soldiers, the principle of preserving human dignity is widely used because a strict environment is dominant in army. Therefore, by adopting an analytico-descriptive approach in this paper we have dealt with how to operationalize the principle of preserving dignity among the soldiers, the methods and also one of the epistemic obstacles and how to remove them i.e. the conflicts and resolving them. Among the findings of the study, we can refer to investigating and criticizing the methods of preventive methods from servile behavior, intentionally showing ignorance and optimistic behavior and also resolving the conflict of apparent, not real. ignorance method by other methods, preserving the principle of dignity, the principle of maintaining religion, the principle of expressing the right in relief, and the principle of being faithful to a secret. The most important result of the study is elaboration on preference of soldiers’ dignity being in conflict with commanders’ dignity in the issue of “expressing the right in relief”.
