During the First World War in Russia, the inventor Konovalov proposed to make armored transporters on the basis of 3- and 5-ton trucks, having chromium-nickel armor with a thickness of 4 and 6 mm, armament from a machine gun in the front turret, embrasures for firing rifles, wheels with metal discs covering spokes, and with a doubled width of the supporting surface, for the transport of 20 people. Engineer Poplavko built several armored vehicles based on the Jeffrey Quad truck, capable of carrying up to 10 people armed with Mauser C96 pistols, grenades and daggers.
During World War II, several armored personnel carriers, B-3, TB-42, BA-22 and others were developed in the USSR, but they were all rather weak because they were based on Soviet trucks that did not have sufficiently powerful engines (during the First World Bobrovsky believed that a 1.5-ton truck should have a 65-horsepower engine and a speed of over 100 kmph, the most massive Soviet 1.5-ton truck GAZ-AA had only 40 hp and a speed of 70 kmph). In 1941, on the eve of the German attack on the USSR, the development of wheeled and tracked transporters was ordered. In the 30s, there were experiments with different transporters based on the T-26 and BT tanks. During the war, the USSR could not afford to produce such equipment, it could not even supply the army with trucks and tractors. It is curious that it was the shortage of armored personnel carriers that served as a reason for the military to abandon reactive armor from 1929 (the first project in the USSR) to 1965, because the infantry rode tanks, and reactive armor was considered dangerous for soldiers (although this sounds more like a strange excuse, but perhaps the real reason was that the USSR had a rather limited production of explosives, even with supplies from the United States and Britain, it could not provide the army with shells and bombs).
