Even after the 1.01 patch, the recoil sound of any weapon is bugged.
10 or 15 shot you here correct gun sounds, then with every trigger you here something different. Names, commands, numbers. For example: You shoot and then you here "AT, AT, AT, AT, AT...soldier, soldier, soldier, move," and so on. It's not only my own weapons, it comes from EVERY weapon across the battlefield and that's VERY annoying.
