The Cruiser tank MkI was designed by Vickers in 1936 to provide a fast cruiser type tank which could move fast with a small gun.
The rear AEC 150hp enginedrove the track over 3 top idlers, around the front idler and back via 2 distinctive 3 wheel bogies.
The Mk I C.S. close support version was the Mk I but with a 3.7 inch howitzer. The vehicle also had two auxillliary machine gun turrets housing Vickers machine guns.

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.
