Twenty British Lung "Tetrarch" tanks (A17) They were sent to Russia. They arrived by land – through Iran. Soviet tankers, these machines are not loved. The company "Vickers" developed "Tetrarch" on its own initiative in 1937 in the framework of «Purdah» project. AT 1938 , the car was put into service in the British Army as a light tank Mk VII. Production began in 1940 year, but soon suspended – It becomes clear, that light tanks were too vulnerable to existing level of anti-tank weapons.

Unlike earlier models of tanks in this class, in the design of the tank "Tetrarch" modified Christie suspension was applied. It allows you to control the front rollers, making tracks bend in the horizontal plane at the corners nekrutye. Using this method allows us to solve the problem of loss of power in the management of the tank slip treads on the ground. If it required a sharp turn, a driver braked a caterpillar, and a tank made with the usual rotation of the outer sliding. Each of the four rollers has a pneumatic shock absorber, desired pressure which must be maintained with the foot pump. In the Soviet Union, these tanks often photographed and used for propaganda purposes.
