Anxiety among soldiers is a phenomenon that has been occurring more than once in many armies. Sometimes such anxiety turns into something worse, such as a mutiny
or even a coup. There are many examples of such events. These phenomena are most often implied by the unstable political, economic or social situation, such as the Spanish Civil War of 1936-1939, the junta of black colonels in Greece, or the revolts of unpaid soldiers in the Polish-Lithuanian Commonwealth. There are certain structures aimed at maintaining discipline in the army within Polish criminal law. These structures include, among others the ultimate military need, the purpose of which is to enforce obedience to an order who resists an order of a commander by the letter of the applicable law. This is a good solution because the commanding officer can have a real influence on the soldier and, consequently, can maintain military discipline. If, however, there was a mutiny in the army it would not
be possible to convict the guilty soldiers for this act, as this crime is not specified by the provisions of the Penal Code. In connection with the above, the author tries to show that it is necessary to adhere to the crime of rebellion in the criminal code to influence the consciousness of Polish soldiers. They should be aware that they would be punished with an appropriate sanction in the event of committing this act.
