General Information
The Inf Tank Mk III was designed in 1938 based on the existing fully tracked Valentine and was in use from 1943 to 1944.
The vehicle was powered by GMC 'Diesel 166HP' diesel powerplant producing 165 HP which could drive the vehicle on roads at up to 15 mph with a range of about 90 miles before refuelling. Its cross country performance was good providing a max speed of about 8 mph and a range of about 36 miles.
It was armed with 1 light machine gun. Its main armament consisted of an Ordnance Q.F. 6pdr 7cwt MKII MKIV which could penetrate 90 mm of flat plate at 400 metres
The Infantry tank MkIII the Valentine was a redesigned A10 to provide an infantry support tank which could move slowly with the infantry to provide AT and machine gun support.
The Valentine IX was the up gunned Valentine V which had a larger turret to accomodate a extra crew member, and had the GMC engine.

History
The 6pdr Mk II—differed from the pre-production Mk I in having a shorter L/43 barrel, because of shortage of suitable lathes. The subsequent Mk IV was fitted with an L/50 barrel, with muzzle brake.

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.
