Today the final renders for the Polish light tanks but with the correct pics for the tier 4.

4TP Tier 1 Light Tank

Typical of many tier 1’s only a 2 man crew.

In 1935 it was decided to create new light tanks for the Polish army. Development was undertaken at the Państwowe Zakłady Inżynieryjne (PZInż) works under the supervision of the engineer E. Habih. The design of the vehicle was strongly influenced by foreign developments, for example the British four-ton Vickers Carden Loyd Commercial Light Tank. In December 1936 the documentation was ready, on the basis of which the creation of the prototype of the PZInż.140 tank began. From the autumn of 1937 to May 1939 the road tests of the vehicle were carried out, but it didn’t enter serial production.

7TP Tier2 Light Tank

Carried a 4 man crew. The 7TP was the development of the British Vickers Mk.E, produced in Poland under license. The machine differed from the original with a more powerful PZIn diesel engine. 235 (Saurer VBLDb), turret and weapons. The first series of machines was made in a two-turret version. In 1935, an agreement was concluded with the Swedish firm Bofors to manufacture a turret with cannon armament of the same firm for installation on a single-turret version of the tank. The first prototype of the single-turret tank 7TP was tested in February 1937. After that, mass production began, and until September 1939, 110 single-turret 7TPs were produced.

10TP Tier 3 Light Tank

Crew of 4. The 10TP continues the theme of TP in the family. * Project of the wheel-tracked tank cruiser of the late 1930s. The project was based on the Christie tank. The prototype of the machine was successfully tested in 1938-39, but with the beginning of the Second World War the work on the tank was stopped and the prototype was destroyed.

14TP Tier 4 Light Tank

Crew of 4. The machine was a development of the cruiser tank 10TP. As in the 10TP, Christie’s suspension was to be used in the vehicle, but in this case it was intended to install only tracks. Work on the 14TP began in 1938. By March 1939, it was planned to build the first prototype of the tank, but because of the lack of a suitable engine, the work was delayed. The tank was never assembled in the metal because Germany invaded Poland in September 1939.
