hotchkiss' role already filled in by 222 - a light vehicle good for early game aggression. a light vehicle not a light tank, mind you, coz that shits penetrable by even a wet noodle. adding it would be redundant.
if you want a REAL light tank, then vote for Pz III.

A good build order for Soviet this patch. Try to upgrade at least one flamethrower on your Penals, allows them to dominate almost every engagement. Tech an AT nade when you see enemy vehicle; usually because T-70 rush is better and at nade slows it down a bit. Keep your conscripts close to your Penals when you do get an AT nade. If you've fallen behind in fuel and your opponent managed to seize them for a good long while, you might want to opt for an SU-76 instead. Or maybe back tech to Support Weapon for AT guns
