I have noticed that, while in arma 2 OA and arma 2 having similar issues to arma 3, the machine Guns on vehicles, MAY in reality be this accurate, however i doubt so.
I noticed that when using the choppers, the Miniguns are Extremely Accurate, and the bullet trajectory is too linear.
At long distances of 1000m, this could be very usefull.
Im sure the developing team did some research into ballistics, and if the weapons are indeed this accurate, then mark this suggestion as void.
However i want to stress that in gameplay experience, the Game ballistic trajectory for HMG is a little too accurate, and the fact that there is little to almost no recoil, makes these weapons overpowered.
