GAZ-AA was a very low-powered 1.5-ton truck, only 40 hp, which was normal during the First World War and in the 20s, but not later. At the same time, all GAZ-AA units were also very weak, and I don’t understand how Buchinsky expected to create such a machine on this base. Even if it was a ZIS-5, a 3-ton truck with 73 hp, it is still very small. Theoretically, 8-ton YAG-10 trucks or 12-ton YAG-12 trucks could withstand such a weight, but at that time the USSR did not have suitable engines of its own production, except for the project of a truck with a steam engine.
Buchinskiy developed another project for a tank with a hybrid diesel power plant:
1x76.2 mm (?), 7x45 mm guns, 8 Maxim guns, 4 DT guns, 1x4 Maxim AA turret, 25 kmph, 30 crews. Maybe, the most dieselpunk tank ever.
