Objectives:
The aim of this paper is to perform an evaluation of the social and living conditions of professional soldiers and their families in Poland at the beginning of the 21st century and two decades later.

Methods:
The research methods used in this study are: literature analysis and review and the method of logical analysis and structure.

Results:
The analysis of the available sources allowed the author to draw the conclusion that the appropriate status level of a professional soldier may realistically contribute to the improvement of the overall state of social security of both the soldiers and their families, as well as of the capacity of the armed forces, provided, however, that the organisational and legal conditions are fully adjusted to their needs both during service and after termination.

Conclusions:
Professional soldiers serve in the conditions that result from currently existing organisational, systemic, and legal solutions that secure the process of realisation of the tasks for: the Armed Forces of the Republic of Poland, the state of Poland, and the North Atlantic Treaty Organisation (NATO). The social and existential situation of professional soldiers and their families is influenced by numerous, different factors, both external (political or economic) and internal (departmental) ones, as well as those connected to the course of performing professional military service: the structure of the armed forces and the types of tasks performed in the country and abroad.
