It is Army Day in Poland, as today the anniversary falls of the triumph of Polish forces over the Soviets in 1920, also called the ‘Miracle on the Vistula’.

One of the main events to celebrate this day is a military parade that goes through Warsaw. Over 1200 Polish soldiers are to march through Poland’s capital, with French, German, Ukrainian, Slovakian and Lithuanian companies also present.

Apart from an infantry presence, heavy military machinery is also to grind its way through the streets of Warsaw, such as Leopard 2A4 and PT-91 Twardy tanks. Over 40 aircraft are to buzz the city, including such flying gems as the F-16, Su-22 and MiG-29.

As tradition confers, August 15 is also the day when promotions are bestowed upon generals. The day was conferred as Army Day in 1923 and remained so until 1947, when it was moved to October 12 to commemorate the Battle of Lenino in 1943. The date was returned to August in 1992.
