Doesn't make sense that in order to level up the launchers in this game you are required to get kills with it. Shot down around 10+ UAVs only to find out the Strela is still on 0/500 XP level 1.
The fact the camos are locked behind levels and it can go up to level 40+ or something, that would take a ton of dedication and time to get all the camo challenges unlocked.
allow us to level up the launchers by shooting down streaks
