by light tanks, such as the T-60 and T-70. A few captured BA-3 cars were used by the Finnish army under the designation BAF A (sometimes also BA-32-1), and captured BA-6 cars under the designation BAF B. Variants The BA-3 ZhD and BA-6 ZhD were designations for BA-3 & BA-6 cars that had been fitted with a rail kit consisting of hydraulic jacks and six railroad wheels. Limited numbers were produced. The BA-6M, built in 1937-1938, weighed 4800 kg and featured a 10mm thick welded, conical turret. A 71-TK-1 radio and 50 hp GAZ-M engine were installed The BA-9 was a lightened (4,300 kg) vehicle based on the BA-6M, built in 1936. The 20K gun was replaced by a 12.7mm DK machine gun (early version of the DShK) and a 7.62 Degtyaryov machine gun was installed in the hull. 100 were ordered, but production was dropped after two prototypes were completed due to the lack of DK machine guns. One prototype was sent to Moscow and the other to Leningrad. The BAZ was an experimental amphibious version of the BA-3. The welded hull was shaped like a boat and two sponsons were placed in the front. Two 389 cm brass screws were installed for use in water. References Zaloga, Steven J., James Grandsen (1984).
