The vehicle was powered by Rolls Royce 'Meteor V12' petrol powerplant producing 600 HP which could drive the vehicle on roads at up to 40 mph with a range of about 166 miles before refuelling. Its cross country performance was good providing a max speed of about 22 mph and a range of about 66 miles.
It was armed with 1 light machine gun , a BESA Machine Gun 7.92mm. Its main armament consisted of an Ordnance Q.F. 95mm Howitzer which could penetrate 59 mm of flat plate at 800 metres
This was the close support machine that could fire High Explosive from the 95mm Howitzer, but its main role was to fire Smoke Shells to hide the movement of the main tank force. | |

BESA Machine Gun 7.92mm (Machine Gun) |
|
|
| | History | |
| | Developed by BSA from the Czechoslovak ZB vz.53 heavy machine gun which used the German 7.92×57mm Mauser ammunition. It was mostly used as the main armament of the Light Tank Mk VIC and Armoured cars such as the Humber Mk I to Mk III.
This 7.92mm gun was used in the armoured divisions as their supply lines were separated from the infantry who used .303 bullets. Once the British started capturing German ammunition this could be immediately used in these tank machine guns. |

An explosion within 8 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's. |
An explosion within 22 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 5 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.
