I bought the bangalore pass and I finished almost all the challenges ,but there is 1 challenge I am trying to do. Hit 5 enemies with Bangalore's smoke launcher I have been trying to do this challenge...
Ideas
You can only find it in the extra weapon supply. So these ones with the black and red characters, special for Assaults. And in the first rounds. It's luck... I think one will be enough for you to have enough points if you do that with the smokes.
I already opened around 30 of these extra weapon supply boxes but when i picked up an epic or legendary attachment nothing happened (extended legendary sniper mag for example).The Challenge isnt progressing.
you're doing this before the bins refill?
Yes, directly after landing.
