Those light armored cars were used also in 1950s in the armies of Warsaw pact countries and China, participated in Korean War.

The BA-11 was a Soviet armoured vehicle designed with the intent of serving as a replacement for its predecessor, the BA-10. It was the first and only Soviet heavy armoured car produced, and it saw very limited service due to production ceasing after the Nazi Germany invasion in 1941. Compared to the BA-10, the BA-11 featured a sophisticated armour design, providing better protection for its crew, and a more powerful engine, which was said to be more reliable. Despite this, it was considered a disappointment as a result of numerous design flaws and technical issues, and its performance in battle was subpar. Further attempts at improvement were made with the replacement of the petrol engine with a diesel ZIS-D-7, but these efforts were ultimately unsuccessful due to the vehicle's poor reputation. In the end, all 17 vehicles built were lost in combat, and the project was abandoned. http://www.redtanks.bos.ru/gallery/d8/d8_4.jpg ( under TB-3 heavy bomber - landing from the low altitude) Specifications of BA-6: GAZ-AAA 6x4 chassis; weight 5,12 t; dimensions 4,9x2,07x2,36 m; clearance 24 cm; crew 4 men; armor 4-8 mm; armament 45mm gun 20K mod. 1932 + 2x7,62mm DT MG; ammunition 60 shells + 3402 MG shells; engine GAZ-AA 40 hp; speed 43 km/h; range 140-265 km.If shot, the front compartment with engine and transmission module can immobilise the vehicle. The center driving compartment containing the driver and another crew member, with the transmission right underneath to, again, cripple the vehicle's mobility. The fighting compartment in the rear with the turret is fully stowed with ammunition with the gun crew, and so a shot there can cause an ammunition detonation that would make short work of the BA-11's life. Many BA-20s were sent to the front with conventional pneumatic tires, no radios and an incomplete set of spare parts.

Also I am trying to find the info about using BA-20s in the War with Japan (1945) and the info about their amount in Soviet army in 1945. How much BA-20 and FAI-M were used in Poland (1939) and during the Winter War (1939-1940)? Please, help! Many armored cars were equipped with radio stations. Also the railway variant BA-64zhd (2586 kg weight) was produced as small serial, but it had low reverse speed. Light armored car BA-64 was much more modern design than previous Soviet armored cars, having armor plates with big slope angles and MG in open turret for AA defense. Also its cross-country ability was excellent. BA-20s were the most common reconnaissance, communication, staff and guard light armored cars in the Soviet army in 1936-1941 and were used during the Soviet-Japanese military conflicts, in Poland (1939) and during the Soviet-Finnish (Winter) war. They were used, of course, in 1941-1945 also. The reconnaissance sub-units of tank, cavalry and infantry units were equipped with FAI-M and BA-20 in 1936-1943. In June 1941 there were 438 BA-20 + 916 BA-20 with radio stations in Soviet army + 376 FAI and FAI-M. Many of these light armored cars, armed only with single MG, were lost during the first months of the war. BA-27 participated in the battles with insurgents in the deserts of Central Asia (1929-1930s) and in the military conflict with China (1929). In 1929 the first Soviet mechanized regiment was formed with MS-1 light tanks battalion, BA-27 armored cars battalion, mobile infantry battalion and air detachment. In 1930 that regiment was re-formed as the 1st mechanized brigade.Entering service in late 1937, the BA-20 became the main type of light armoured vehicle of the Red Army. First of all, these equipped motorized armoured reconnaissance brigades and mechanized corps, gradually replacing the FAIs. No BA-20s were sent in Spain. In June 1941 the Soviet army still have those obsolete armored cars, mainly at training schools. They were used in combats with Germans in summer 1941 and almost all were lost. T-34 (Prototype) · T-34 (1st Gv.T.Br.) · T-34E · T-34-57 (1943) · T-34-85E · T-34-100 · T-44-122 · TO-55 · T-55AM-1 · T-72AV (TURMS-T) BA-64e (1943, 8 copies in several modifications) – troop-carrier (1 + 4-6 men) without turret, equipped with the door in the rear. Armament – 1 x 7,62mm DT MG or 37mm cannon (planned). Three BA-64e were used at the front, but they were cramped for the crews.

Specifications of BA-11: ZiS-6k 6x4 chassis; weight 8,13-8,6 t; crew 4 men; dimensions 5,295x2,490x2,390m; clearance 26,5 cm; armor 8-13 mm; armament 45mm gun 20K mod. 1934 + 2x7,62mm DT MG; ammunition 104-114 shells + 3014-3087 MG shells; engine ZiS-16 93 hp (one BA-11 had diesel ZiS-D-7 99 hp); speed 64 km/h; range 178-316 km (420 km with diesel). Armour is only sufficient against rifle-calibre machine guns, anything more will shred the car apartAlso the light armored car FAI-M was produced in 1938-1941, based also on GAZ-M-1 chassis (weight 2,0 t; dimensions 4,31x1,75x2,24 m, armament 1 x 7,62mm DT MG with 1512 shells; speed 90 km/h, range 315 km). FAI-M presented the shift of armored hull from FAI armored cars (based on GAZ-A passenger car) to more powerful GAZ-M-1 passenger car chassis, that is why the hull of FAI-M was much more shorter than the new chassis. More than 300 “hybrids” FAI-M was produced that way. The majority of FAI-M was not equipped with the radio station. This is actually a very pleasant change when compared with the big six wheeler armoured cars. The suspension is so much simpler and nicer to build and on the whole a lot less of a bind. All in all a very nice little kit that most modellers could build in a weekend or less, depending on their abilities, great for keeping the mojo. Very highly recommended BA-64 saw the service at first near Bryansk, Voronezh in 1942, in Stalingrad. Later it was used in Poland, Hungary, Romania, Austia and Germany in 1944-1945. 81 BA-64 had Polish, and 10- Czechoslovakian troops in Soviet service during WWII.

In 1932 the new medium armored car BAI (D-13 with new shape of the welded hull) was developed in Izhora and produced in 1933 (90 copies).The next experimental model LB-23 (1939), very similar to BA-21, was equipped with powerful “Dodge” engine (72 hp, later it was produced in USSR as GAZ-11) and had weight 3,5 t, dimensions 4,226x1,778x2,268 m; crew 3 men, speed 71,5 km/h and range 238 km. LB-23 was not very reliable, had bad visibility also its maneuverability was not answered the purposes of reconnaissance. The BA-20 was armored car developed in 1934 for use by HQ staffs, reconnaissance and communications units. In 1934 BA-3 appeared as the modification of BAI, which had better armament (turret from the light tank T-26 with reduced armor). It was the first mass production medium armored car of the Red Army.
