General Information
The PzKpfw IV Ausf A SdKfz 161 was designed in 1936, manufactured by Krupp, Vomag, Nibelungenwerk based on the existing fully tracked PzKpfw IV and was in use from 1937 to 1941.

The vehicle was powered by Maybach 'HL120 TRM' petrol powerplant producing 250 HP which could drive the vehicle on roads at up to 19 mph with a range of about 120 miles before refuelling. Its cross country performance was adequate providing a max speed of about 10 mph and a range of about 48 miles.

It was armed with 2 light machine guns which were 7.92mm MG 34s. Its main armament consisted of a 7.5cm KwK 37 L/24 which could penetrate 54 mm of flat plate at 800 metres

Burst radius Infantry in open 33% kill16 mtr  Armour Penetration inc roof at 1 mtr1 mm
An explosion within 3 mtr of infantry in the open will cause 99% casualties - lethal.
An explosion within 6 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's.
An explosion within 16 mtr of infantry in the open will cause 33% casualties.
The blast effect of this shell exploding within 1 mtr of an armoured vehicle will penetrate 1 mm of the tank armour including the roof.

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.
