It was commonly called a Skoda S-IIa/T-II. It was armed with 2 light machine guns. Its main armament consisted of an Skoda 37mm P.U.V. vz34 L/39 which could penetrate 37 mm of flat plate at 400 metres The Czech army placed an order with Skoda in October 1934 for a medium tank. The first trial vehicles were delivered in spring 1935, and were found to have many faults, these machines were returned to Skoda for modifications. An order for 160 was placed in October 1935, and a further batch of 138 were ordered during 1937. These vehicles were also ordered by Romania who took 126, these were called the R2. The Skoda factory was taken over by Germany during 1938, and a further 219 were built for the Panzer Divisions. The vehicle transmission sprocket was at the rear, the track passed over 4 track return rollers to the front idler, then down over 8 road wheels on two bogies. Compressed air was used to help the transmission and steering, but this system had problems when used in low temperatures such as found on the Eastern Front. The main armament was the Skoda 37mm P.U.V. vz34 L/39 anti tank gun in the turret.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
