During August I managed to get out of Prague for the day and drive down to the Czech Army Military museum in Lesany (about 50 KM south of Prague). The museum houses a large collection of tanks and artillery from around the world, especially WW2 German and Soviet tanks and artillery. Above you can see the famous "Pink Tank". This was on a Soviet War memorial in the centre of Prague, and a couple of years after the Revolution was repainted pink by the Czech protest artist David Cerny (the tank was on a 1945 liberation memorial, and it was a play on how the Soviets went on to "Liberate", and then occupy the country after 1968). The Russian Embassy was outraged and protested, so finally the tank was moved to the museum.
The museum really does have a huge collection of interwar, WW2 and cold war tanks (especially British equipment used by the Free Czechoslovak Army in WW2). They also keep a large number of them in running order and put on exhibitions of them driving around the training grounds in the summer. I will just list the tanks below against pictures and some commentary. I highly recommend this for a day trip from Prague.

The 1933 Skoda MU - 4 interwar tankette (it really is the size of an armoured mini). Below you can see the Czech designed AH-IV tankette, which was used by the Romanian, Swedish and Iranian Armies in WW2. The one in the photos is the Swedish version.
Below, the famous Czech LT- 38 (used in large numbers by the German Army at the start of WW2). This was an extremely reliable light tank, and in terms of engineering and mechanics, far superior to anything the Germans were producing at this time, certainly much better than the Panzer I and II tanks. It saw extensive action during the invasions of Poland, France and the Low Countries.
The chassis continued to be used throughout WW2 in the production of Marders and Jagdpanzers.
Below, a Jagdpanger (38) Hetzer, based on the Czech LT-38 Chassis.
