BA-11

The BA-11 or Broneavtomobil 11 (Russian: БА-11 or Бронеавтомобиль 11) was an armored car developed in the Soviet Union. It was intended to replace the BA-10, but production was prevented by the Nazi German invasion of 1941. The BA-11 was a heavy armored car designed based on a strengthened ZiS-6K chassis. Used during 1941-1942 on the Leningrad front, it was designed to attack infantry, cavalry, and medium armored cars. With 13mm of frontal armour, it was only slightly less protected than the most common soviet light tank of the era, the T-26, which had 15mm of armour.
