Newly added M1 Bazooka for USSR is a non-upgradeable weapon and there are very much pointless and useless squad upgrades for this weapon that even if a player unlocks them, they do absolutely nothing.
Just look at the screenshot, we can “upgrade” from 2 stars to… 2 stars, but technically there is not even an option for upgrading.
My question is why even add these upgrades to the game? In the USA tech tree the identical M1 Bazooka doesn’t have these upgrades, same as all other similar weapons like Panzerfausts, Piats and some other AT weapons.
