So. In my understanding breacher MUST have some advantage over rifleman, at least in CQ. It works with securitie's mp7 - all-around good gun. But why does aks-74u exist? What is it's advantages over ak-74m for example? I didn't notice a better recoil, quicker ADS, faster movement speed or more accuracy from the hip. Or am I wrong here?
It exists, because Soviet union needed a short, simple and cheap gun for vehicle crew self defense. Using a common ak74 inside a btr, uaz, tank is very complicated
In game terms, shorter the barrel - easier to cut corners properly. Also breacher can carry explosives, and common rifleman can`t.
