[3] In the Red Army, they were used to perform tasks in communication, reconnaissance, and as defense units on the march, as well as active infantry support on the battlefield.

Surviving tanks fought on the front lines until 1944, and were used in training and auxiliary defense until the end of World War II.

At the Bolshevik OKMO plant in Leningrad, from the All Russian Co-Operative Society (Arcos), newspapers were handed in containing information about the British tankette, as well as photographs and technical specifications.

[citation needed] Based on this information, Soviet engineers found out that the power plant of the Carden-Loyd tankette was originally from a light tractor produced by the company, and thus the overall layout must be similar.

Селезень) program was established in order to construct a similar amphibious tank with a layout based on that of the British prototype.

Although the T-41 was actually produced for the military in small numbers, after testing and battlefield trials the T-37 was denied production due to various minor faults and an incomplete development process.

The British Army declined to put the Vickers prototype into service (although they were used as trials vehicles), and so the company decided to look for foreign buyers.

Already interested since the April 1931 demonstration, the USSR, on February 5, 1932, made an offer, through Arcos representative Y. Skvirskiy, for the purchase of eight vehicles.

However, closer examination of the turn of events leads to the discrediting of such a theory, but it is true that the Soviet T-37A prototypes were heavily influenced by the British models.

Nikolai Astrov, a Soviet engineer, having worked hard on the T-37A prototypes, wrote in his memoirs that "peace be unto the T-37A, born “Vickers-Carden-Loyd.

The trust itself was formed as a governing organ for coordinating large-scale efforts to develop new models of armored vehicles in a number of plants across the country, and subsequently played a significant role in the successful carrying out of this task, but at the beginning of 1933 it couldn’t overcome the “antediluvian” state of equipment at the No.

The technology for producing stamped cemented armor plates at the Podolsk plant was completely unrefined; the desired result had to be achieved using improvised and primitive methods.

As a result, mid 1934 was marked by a change in leadership of the plant, and only towards the end of the year there had been a positive trend in the manufacturing process.

Also, in 1934, slight changes were made to the T-37A design: the thickness of the sides and the front were increased to 10 mm, the curved stern piece hulls were replaced with stamped ones, and the over-track floats were rolled back and stuffed with cork, and they have become empty on the inside.

The Podolsk Electric Locomotive Plant consistently failed to fulfill the plans for the production of parts in adequate numbers.
