The research problem and the objective of the study determined the structure and content of the article and, consequently, the nature and content of the postulates presented in the summary.

The aim of the article is to identify the conditions of the scope of logistics activities performed during the handling of returns and complaints, and to show the possibility of implementing modern system technologies in the management of logistics processes. The research problem undertaken was specified as follows: "What is the essence of managing the logistics process of returns and complaints based on IT infrastructure in the enterprise?" While preparing the article, the method of examining the content of documents and the method of analysis, including statistical analysis and literature review, were used. The first part of the article presents the results of the research on the requirements and standards of modern logistics management through the prism of its selected systems as well as the functions and tasks assigned to these systems. The second, main part of the article concerns the importance and requirements for IT infrastructure used in the logistics processes of returns and complaints. This section also highlights the impact of the RFID environment on the functioning of logistics processes for returns and complaints in commercial enterprises.

The article presents selected examples of implementation of support tasks by the host nation support for the benefit of allied and partner troops, performing tasks on the territory of Poland, resulting from the new geopolitical conditions in which Central and Eastern Europe found itself. The resulting threats and dynamics of change forced the Alliance's authorities to take a new approach to strengthening NATO's eastern flank as part of improving the region's security. As a result of the actions undertaken, the exercises in Poland and the Baltic countries, the relocation of allied troops by our territory and their deployment as a result of the eFP (enhanced Forward Presence) and Operation Atlantic Resolve were intensified.

As a consequence, the increase in the involvement of the alliance in the performance of tasks on our territory requires increased participation in the HNS, not only the military system of the state, but also involvement of the non-military defense system of the state.
