February 15, 1989, the last Soviet soldier left the territory of the Democratic Republic of Afghanistan. The ten-year Afghan war is over...But even now, after 30 years, the history of this war is covered with white spots, one of which is the participation of Soviet border guards in it. The very fact of the participation of the “green caps” in that now half-forgotten war was carefully hidden by the leadership of the State Security Committee, and only relatively recently eyewitnesses of those events began to share their memories. In this book you will not find detailed historical analysis and statistical calculations, comments from venerable political scientists and prominent politicians. Here is only the truth on behalf of the soldiers and officers who wore green caps and green shoulder straps. In an effort to protect the southern borders of the Soviet Union, the leadership of the KGB of the USSR sent these soldiers abroad, setting the task of preventing the fire from spreading from the territory of blazing Afghanistan. And this task was completed in full!
