As air to air manoeuvres take the relative motion into play, many times gun shots fired directly at the target miss it due to the constant movement of the target and the chasing pilot feels that the shot is late to reach the target meanwhile target has moved from that location.

The most common way to correct this issue is to anticipate in which direction the target is moving and try to shoot in the future path of the target anticipating that if target follows the same path in future then there would be a higher probability of hitting the target.

To counter this, the target has to constantly alter the trajectory
