The Panzerkampfwagen 35(t), commonly shortened to Panzer 35(t), was a Czechoslovak-designed light tank used mainly by Germany during WW2. The letter (t) stood for tschechisch (German: "Czech").  A total of 434 were built; of these, the Germans seized 244 when they occupied Bohemia-Moravia and the Slovaks acquired 52 when they declared independence from Czechoslovakia at the same time. Others were exported to Bulgaria and Romania In German service, it saw combat during the early years of World War II, notably the Invasion of Poland, the Battle of France and Operation Barbarossa before being retired or sold off in 1942. It was used for the remainder of the war by other countries and as a training tank in Bulgaria into the 1950s.
