The theme of this papper is a special condition and status of millitary personnel in Croatian Armed Forces. Through a brief introduction and development of themes we will see all the particularities of the military system; and off course how does it differ from the civil system of work in the Republic of Croatia.The most important regulation in Armed forces: “Regulations on military service” is described in the next chapters to understand the problem of work in a closed system such as the army. Furthermore, the text is unclear division of personnel in the Armed Forces and the service status. Military disciplinary courts are the specialty of this system and the explanation, as well as a disciplinary punishment. One of the most interesting items will be the theme of the official assessment , which is the crown of the business - the military itself carries a lot of changes during the service, accordingly, it will has a great importance in this work. I’ll also write about the decision of the Croatian Parliament that abolished the regular rookie military service, and has introduced a brand new training program for the rookies. Towards the end of the topics we'll list the differences between civilian and military systems, and describe the advantages and disadvantages of the same. At the end of the paper we will describe is brief personal reflection on work in the military system, why is it specific, and therefore differs from the work in the civilian system.
