The vehicle was powered by Praga 'EPA/2' petrol powerplant producing 150 HP which could drive the vehicle on roads at up to 26 mph with a range of about 156 miles before refuelling. Its cross country performance was good providing a max speed of about 15 mph and a range of about 60 miles. It was armed with 2 light machine guns which were ZB vz.53 or MG-37(t)s and ZB vz.53 or MG-37(t). Its main armament consisted of an Skoda 37mm P.U.V. vz38 L/39 which could penetrate 46.2 mm of flat plate at 200 metres. In use by the Czechoslovakian army until 1938/39 when all were seized by Germany after the invasion.

In German use this gun was known as the MG-37{t} Manufacturer Zbrojovka Brno Manufactured 1939 - 1966 Calibre 7.92mm Length L/93 Rate of Fire 450 rpm Number of Rounds  2400 Ammunition Details Name/Id Calibre Weight MVelocity Explosive Content S.m.K.H tungsten cored (AP Standard Small Arms) 7.92mm 0.013Kg 910M/Sec Quoted Penetration 13mm@100m/30° Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.11 0.22 0.44 Penetration(mm@30°) 7 6 5 Penetration(mm@0°) 9 7 6 Hit Probability(%) 74 74 74 S.m.K (BALL Standard Small Arms) 7.92mm 0.012Kg 785M/Sec Quoted Penetration 8mm@100m/30° Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.13 Penetration(mm@30°) 1 Penetration(mm@0°) 2 Hit Probability(%) 74 About Penetration Figures All penetration figures in this database are calculated to a common standard based on German WWII testing criteria (complete penetration with functioning fuze). This allows direct comparison between all nations' guns. Original national test figures would be higher for some nations due to different criteria: German: 1.00? (baseline - strictest) British: 1.02? (slightly looser) American: 1.05? (50% mass through plate) Soviet: 1.10? (75% mass through plate) For example, a Soviet gun showing 159mm here would be published as ~175mm in Soviet documents, and a German gun showing 120mm would be published as 120mm in German documents. The 159mm figure is directly comparable to the German 120mm - the Soviet gun really was more powerful. National Testing Standards German: 1.00? - Complete penetration, fuze functions (strictest) British: 1.02? - Complete penetration American: 1.05? - 50% of shell mass through plate Soviet: 1.10? - 75% of shell mass through plate All database figures are normalized to German standard for direct comparison. Multiply by the factor above to see original national test figures.

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.
