Abstract
Nowadays the Romanian Armed Forces are subject to a process of modernization of the defence capabilities, and the process is mainly focussed towards the military assets. However, the human factor is decisive in manipulating the new military technology in accordance with its technical specification. In this context we assess that the process of ensuring the proper human resource is a vulnerability factor, and therefore we tackled the demographic decline as a threat for our national security, as it has been less studied in the last period of time. Considering this social phenomenon as one of great importance for our national security, we conducted a research that would lead to pertinent conclusions regarding the trend of the demographic decline and would provide solutions to increase the number and the quality of human resource selected for the military system.
