This work allows to trace the origins and growth of the structures of Military Intelligence of the Armed Forces of People’s Republic of Poland. It shows numerous, especially since the 60s, changes in the structures, naming, and assigning of departments. The time range that has been covered is the period since the origin of the communist military intelligence, that is, 14 May 1943, when on the order of, then still Colonel, Zygmunt Berling, 1st Reconnaissance Company was appointed. End occurs when the Minister of Defence ordered on 22 August 1991 to exclude the Second Directorate for Intelligence and Counterintelligence, from the structures of the General Staff and appoint Inspectorate of the Military Information Services (WSI), which answered directly to the Minister of National Defence. This is where the history of the communist intelligence service ends, however the communist system has theoretically finished over two years ago.
