"...if in America the main mythology on which 'emotion management' was based was a mythological narrative of home and family, its equivalent in the USSR was a state imposed narrative that found its embodiment in the system of military training in school and higher education institutions. Recollections collected from the Russian participants show that the dominant patriotic collective narrative was sustained by means of military and patriotic education. This education was conducted both in and outside the school by means of school curricula, clubs and societies of revolutionary and labor glory, paramilitary Summer Lightning and Eaglet games, excursions to scenes of revolutionary combat and labor glory of the Soviet people, Red Scouts activities, GTO norms, and paramilitary summer camps. School and university teachers, whatever subjects they taught, were supposed to participate in these methods of political socialization and character training. In the course of military games, children were taught to measure levels of radiation, to locate radiation-free areas, and to render general assistance to the public during a nuclear crisis. "What were we thinking at that time? - one of the participants asks herself - We were supervising how good our pupils are in obeying orders from their officers. Did we think at all that we need good citizens, independent people, not good soldiers?""
