Russkies produced their light tanks in automobile/bus factories, and produced them like hot rolls. So when they figured out that T-70 is outclassed on the battlefield, they constructed SU-76 (76,2mm zis-3 cannon was produced in 100 000 pcs during 3 years ). Et voila, one has a design that is both usable and lends itself to be produced in 'ordinary' factories - while Germans produced similar stuff in 'proper' heavy-machinery factories.
The SU-76 chassis was a base for development of M-60 APC for ex-Yu army.
