The vehicle was powered by Guiberson 'T1020' diesel powerplant producing 250 HP which could drive the vehicle on roads at up to 36 mph with a range of about 130 miles before refuelling. Its cross country performance was good providing a max speed of about 20 mph and a range of about 52 miles.
It was armed with 3 light machine guns which were 0.3 inch Browning Machine Gun M1919A4s. Its main armament consisted of a 37mm Antitank Gun M6 which could penetrate 71 mm of flat plate at 100 metres
The Light tank M3 Stuart II was a tank based on the M2A4 with an upgraded 37mm anti tank gun later models having a gyrostabiliser.
The power was provided by a 250hp Guiberson diesel engine, driving through the front drive wheel, then via 2 pairs of road wheels to a rear idler then back over 3 return rollers.
The models varied from the early rivetted models to the very late fully welded models. | |

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.
