SU-122 (USSR, Tier-6, Assault SPG, techtree)
Historical Reference:
The SU-122 was developed in 1942 due to a critical need for a powerful and highly mobile fire support vehicle for tank and mechanized units on the front lines. On November 30 of the same year, the Ural Heavy Machinery Plant presented a prototype based on the serial T-34 tank, armed with a 122-mm M-30 howitzer. In December, the self-propelled gun (SPG) entered mass production. It became the first medium SPG in the USSR to be produced on a large scale. Production ceased in August 1943, with a total of 636 units built.
