General Information
The Cruiser MK VIII was designed in 1942, manufactured by Rolls Royce based on the existing fully tracked Cruiser Tank and was in use from 1944 to 1950.

The vehicle was powered by Rolls Royce 'Meteor V-12' petrol powerplant producing 600 HP which could drive the vehicle on roads at up to 32 mph with a range of about 120 miles before refuelling. Its cross country performance was good providing a max speed of about 15 mph and a range of about 48 miles.

It was armed with 1 light machine gun , a 0.3 inch Browning Machine Gun M1919A4. Its main armament consisted of an Ordnance Q.F. 17pdr which could penetrate 186 mm of flat plate at 200 metres

The Challenger tank was designed as a heavy cruiser tank that could rapidly move and provide good A/T performance, in appearance it looked like the Cavalier.

The vehicle had a rear Rolls Royce Meteor engine producing 600hp driving the tracks, towards the main front idler over the 6 large road wheels, round the idler and back under the roadwheels in the standard Christie style.

The Challenger was a redesigned Cromwell designed to take the 17pdr AT gun, however too many changes were needed and only a few vehicles saw service.

An explosion within 2 mtr of infantry in the open will cause 99% casualties - lethal.
An explosion within 5 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's.
An explosion within 13 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.
