That does not contribute anything to the discussion then.
Until the SU76 finds a proper, usable role in the Soviet rooster again, it is not relevant for the current discussion.
...
Zis barrage is the counterpart of Brumbar: an assault gun unit Soviet are lacking in its roster. ...
Imo it does it proves this argument to be false, since SU-76 is an assault gun.
The reason zis even has barrage a barrage has nothing to do with brumbar.
It comes from the original Soviet designed that wanted some of the stock soviet units to be "jack of all trades and master of none"
The problem started to appear when some of these units become good at their role while keeping their extra utility.
In the case of zis one can start but increasing the CD of barrage and either moving to Vet 1 or removing the mini map info from tracking since the combination of barrage and "map hack" should not be available.
