1st Czechoslovak Partisan Brigade of Jan Žižka

The 1st Czechoslovak Partisan Brigade of Jan Žižka (Czech: 1. československá partizánská brigáda Jana Žižky), initially known as Ušiak-Murzin Unit, was the largest military unit conducting guerrilla warfare against the German occupation forces in the Protectorate of Bohemia and Moravia (modern day Czech Republic) during the Second World War.The brigade was named after Jan Žižka, the 15th century leader of the Hussite army whose use of innovative techniques, such as the wagon fort and the large scale use of firearms, made him a Czech national hero. During the Second World War, there were two additional partisan formations that separately also used Jan Žižka's name: the Jan Žižka Moravskoslezský (formerly the Bílá Lvice resistance unit), operating further north in the Czech lands, and the Czechoslovak Brigade of Jan Žižka in Yugoslavia, operating in the Balkans.
