SU-76 and SU-122 Production

This is quite a wide-reaching decree, dealing with three tanks: the rise of the SU-35 (SU-122) and SU-12 (SU-76), and the end of the T-70, as the SU-76 was replacing it as a cheap infantry support method. Also, it lists the large (very, very large) amount of steps and people involved in manufacturing a new tank.

Ultimately, neither vehicle went on to become very successful. The SU-76 ceased production in 1943 due to poor reliability, replaced by the SU-76M. The SU-122 was replaced with the SU-85 in 1943 as well. As for the T-70, no additional production resources were found, and its production also ceased in 1943.
