The Moscow Victory Parade of 1945 (Russian: Парад Победы, tr. Parad Pobedy) was a victory parade held by the Soviet Armed Forces (with the Color Guard Company representing the First Polish Army) after the defeat of Nazi Germany. This, the longest and largest military parade ever held on Red Square in the Soviet capital Moscow, involved 40,000 Red Army soldiers and 1,850 military vehicles and other military hardware. The parade lasted just over two hours on a rainy June 24, 1945, over a month after May 9, the day of Germany's surrender to Soviet commanders. Despite 800 000 women serving in the Soviet armed forces, no woman was allowed to march during the parade.
