Hi i don't know why but pre 9.6 when using vanga/achilles aim the crosshair used to aim in front of moving tanks now it is useless it just aims at the tank so misses by miles when shooting, what should the settings be set at to lead the tank.
May be your ingame aim button equal to vanga aim button. Change aim button in game settings
Vanga aim is useless now against moving targets, it's almost as bad as Achilles, please sort this out
