What sort of fucking scaling does it have? a barrage that your 0 fuel AT gun has, and boasts basically an equal health durability with superior AT stats to boat.
So you are just going to pull an atgun from the backline? you have a very good chance that you will lose the at gun if even a single infantry units catches up with it.
80% of su-76's will not reach vet 3 and those that do should be rewarded for it, losing one, which is really fucking easy btw, means that you'll never deal with a """""160""""" damage SU-76 for the rest of that particular game
High dps with low vet requirements its very easy to get a su76 to vet 3.
