If tanks are out of red cirle. Even if the p47 spots them. it WONT fire.
Edit: there is also a way to trick the plane. If u see the direction the plane is attacking from. u can face ur tank twards the p47. revers while blitzing. then sharply turn. More rockets will miss. This only works if one p47 has been shot down. If the planes attack from both sides. then ur out of luck.
then how come it still randomly attacks even when you drive to the other side of the map?
