I played BF4 a long time ago and I wanted to play it again, so I bought it and I got premium and once I launched the game I remembered there was a bow in the game, so I wanted to get it. I have been playing the game I when I looked at the missions, nothing had progressed even though I have killed at least around 200 people with ARs. Am I missing something or is it bugged? Any help is appreciated.
