The first rehearsal of parade units on foot took place on Palace Square in St. Petersburg in preparation for the 81st anniversary of Victory in the Great Patriotic War. Units of the Leningrad Military District, cadets from military academies, and representatives of law enforcement agencies participated in the training. The specialists practiced their marching skills and drill techniques accompanied by a combined military orchestra. On May 9, 1945 (Moscow time), the Act of Unconditional Surrender of Germany came into force. For city residents, this date is inextricably linked with the heroism of the Leningraders who survived the siege.
