General Information

The Inf Tank Mk III was an Infantry Tank designed in 1939, it was based on the fully tracked Valentine chassis and was in use from 1942 to 1945. It was commonly called a Valentine VII.

The vehicle was powered by GMC '6004' diesel powerplant producing 165 HP which could drive the vehicle on roads at up to 15 mph with a range of about 0 miles before refuelling. Its cross country performance was adequate providing a max speed of about 8 mph and a range of about 0 miles.

It was armed with 1 light machine gun. Its main armament consisted

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 turret had power traverse with a 2pdr A/T gun. The armour was good for this size of vehicle. The Valentine VI was as per the Valentine II but with the GMC diesel engine, external fuel tanks and studded tracks and were made in Canada.

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.
