Polish extended tech tree for World of Tanks proposal by PikPikker and Zinoviy Alexeev Blog

Col. Chrobok’s first design was submitted in December 1940 while residing at the Polish Army camp in Rothesay, and titled ‘Improvements Relating to Automobile Gun-Carriages.’ The object of the design was to provide heavy and light ordnance in the tank along with a contingent of foot troops and other portable equipment such as light field guns all in one package.

The front of this first design would concentrate its armament with a wide array of guns consisting of heavy armour-piercing guns, heavy machine guns, flame throwing devices and anti-aircraft guns as thought fit. The entire vehicle was to be armor plated, with special care being given to the crew cabin. The rear troop area of the vehicle was specified to have armored sides and, depending on the requirement, would have either a waterproof fabric cover or an armored roof.

Inside the rear troop compartment were a series of stepped bench-seats arranged longitudinally for troops with a storage area underneath for equipment. The whole area was accessed through a large rear hatch which could hinge either downwards or outwards. The side walls were also intended to open in order to facilitate loading or offloading as the vehicle was also intended to move supplies and the wounded on stretchers. The complete specification for this patent application was complete by 27th December 1941 and it was accepted on 6th July 1942 under Patent number GB 546,287(A).

Note that this is multi-turreted vehicle. In-game, the bigger front turret wil be considered as main turret and two smaller front turrets will be considered as secondary turrets.

In January 1941, Colonel Chrobok submitted a second and improved variation of his first design, this time titled ‘An Improved Armoured Gun Carriage.’ The most substantial change brought by this improved design was the addition of a small round turret at the rear of the machine, which was to serve as an anti-aircraft gun. A less obvious difference was the addition of two parallel longitudinal firing ports on each side of the troop compartment, permitting the troops to fire from within.

The last hybrid tank/APC designed by Pawel Chrobok in 1943 under the title "Improved Armoured Gun Carriage". This new tank design was intended to fulfil offensive and defensive roles and equipped with, according to Chrobok, “very powerful offensive armament.” With a similar frontal aspect to the previous designs, this design specified that the cylindrical gun turrets (one or more) would be sunk into the body and have a diameter of approximately ⅓ of the overall vehicle width. Specifically, there would be an overlap on the side walls in order to provide buoyancy and the large amphibious design would be propelled in the water by its tracks.

Note that this is multi-turreted vehicle. In-game, the rearmost turret will be considered as main turret, and one of two other turrets (mid or foremost) will be considered as secondary. Also, in-game its secondary double-barreled gun will only be able to fire double shots.

Early concept of super-heavy tank designed by Stanislav Lem in 1944, also known as "Huge sized tank" (Czołg wielikih rozmiarów) or "Battleship tank" (Czołg Pancernik). Didn't passed through conceptual design phasee.

The design of super-heavy tank weighting about 220 tons was created by Stanislav Lem in September 1944. The tank was supposed to have six turrets — main turret with single large-caliber gun, secondary turret with two light AA guns and four machine gun turrets. It should have thick rounded cast armor plating and its chassis consisted of four independent caterpillars. It didn't passed through design stage.
