This is pretty interesting. Where was this? Across the USSR. Lithuania was a part of it during my school years (except for the last couple of months, Lithuania proclaimed renewed independence in March 1990, I graduated in June) and we had this course too. We even had two-weeks of kind of military camp after the 10th grade.
