| Notes | The BT-5 was classed by the Soviets as a fast cruiser tank and this speed was mainly down to the suspension system that was designed by the American Walter Christie. It also built as a convertible tank and ran on large road wheels which could run on either tracks or on their own. It had a two man turret and mounted a 45mm gun. It was considered the fore runner for the T-34 and was produced in large numbers, due to the numbers in service it saw action on all fronts and suffered grave losses against the Germans mainly due to thin armour and bad handling. |
