SU-76 is cost-efficience.
But the reason why back tech for Zis gun is better optine because it will not delay T4 tech.
/tread.
Yes and that's the problem, current su-76 doesn't perform good enough to persuade players sacrificing their t4 timing to get it. Back teching for zis is always better even it cost 2x manpower.
Cons and penals struggle to fight grens and vgrens when the axis infantry has weapon upgrades. So as soon as you reach t3 you get a t-70 to help you deal with infantry and weapon teams, because it has anti-infantry power which soviet needs in mid game.
Su-76 can use a rework to be come a mobile indirect fire platform with ability to deal with light vehicles.
Rework the orginal barrage to let it fuction like scott in limited time and grants it smoke barrage, then it can help soviet infantry fight well-armed axis infantry. It shouldn't be counter to mediums so nerf the penertration to that of pumas.
If su-76 is to be reworked as a support vehicle, then it can create diversity in soviet t3 game play. Either use t-70 to chase and hunt down infantry and team weapons, or use su-76 to get indirect and smoke support and shut down light vehicle at range.
The problem of this unit is its role. When sov reach t3, it always urges for anti-infantry firepower.
