I want the SU-76 to be an assault gun. IMO my solution to make it viable is give it sherman HE rounds as a free ability that stops the vehicle from moving.
"Give rear echelons some love" - remove crews form usf vehicles and trust me they will be more than loved
to the post - remember that soviets are the best atm and su-76 is a skill unit for micro pros. Buffing it may result in overbuffing the whole faction imo
