Thxfully we have the changelog thread and it's as easy as doing a control + F.
3 changes made it good.
- Soviet rework. The whole dichotomy of only getting 2 tiers, made the vehicle tiers arrive at a certain point which limited lighter ones. Putting M5, T70 and Su76 on same tier, allowed it to arrive at a sensible time.
- 200% buff to suppression. Yeah, it was bad.
- 50% buff to damage.
I remember it would literally hit vet 3 almost immediately and always forced instant retreats of all axis infantry.
Shit was actually insane
It also killed OKW set up trucks in 2 bursts if Im recalling correctly.
